b2ap3_thumbnail_Pneumatic_Actuators.jpgA pneumatic actuator works by converting energy, which is usually in the form of compressed air. When it comes to pneumatic actuators, they offer a number of advantages to the users.

Listed below are few of the benefits offered by these types of actuators:

Components – Another major advantage offered by pneumatic actuators is their simple design and operating components. They are not just easily available, but are also relatively inexpensive & low priced.

Heavy loads – These actuators can easily tolerate heavy loads, and are thus, quite commonly used in a number of applications.

High force & speed – When used in linear motion control applications, wherein high precision is not a much essential parameter, these actuators offer high force and speed, which is difficult to find in any other actuator, except the hydraulic ones.

Easy accessibility of the source – For any pneumatic system to work, air is a major source. Easy availability of this source makes pneumatic actuators the preferred choice of many.

Easy channeling – Apart from being easily available, air can also be channeled and routed from one place to another. Thus, using the pneumatic actuators becomes easy through easy channeling of the source.

Safe to be used – Pneumatic actuators are safe to be used. Thanks to the use of air, they are not flammable and are not susceptible to short circuit, in contrast to the electric actuators.

Storage functionality – It is great to understand the fact that as the pneumatic actuators contain just compressed gases, they can be stored even in the absence of electricity or power. Thus, the users get another benefit with their use.

Clean technology – These types of actuators offer a clean technology to the users as they are less prone to contamination. Due to the use of air, which is free from harmful chemicals the pneumatic systems are quite well known in the food and pharmaceutical industries.

No overheating issue – The pneumatic actuators do not overheat upon excessive use, and are thus favored by many users in applications that require longer use.

Cost-effective substitute – A pneumatic actuator is said to be a cost effective tool for systems. With its easy installation and maintenance, it has become a great option to go for when you are looking for inexpensive actuators.

High durability – Another benefit of having pneumatic actuators is that they offer a long term use, thanks to their high durability. It’s good to note that these actuators can easily sustain constant pressures, which is great when you compare them with the other types of actuators.

b2ap3_thumbnail_0108.gifBefore understanding the concept of a solenoid valve, we should first understand what a valve is.

A valve is a device which works by regulating or controlling the flow of a fluid. This fluid can be liquid, gas, slurry, etc. Valves are available in a wide variety of makes and designs, serving a variety of purposes.

Now, a solenoid valve is just the combination of a solenoid and a valve, which regulates the movement of gas or liquid by means of electric current. This electromechanical actuator stops, releases, distributes or combines fluids; and is being extensively used in a number of application areas.

Components of a Solenoid Valve

A Solenoid Valve has parts like a coil of wire (which is the Solenoid), a metal core, electrical connector, bonnet nut, body, etc. These components are necessary for the efficient functioning of the valve. In case a malfunction occurs in any of the parts, the operation of the valve will not be effective.

Hence, it should be checked regularly that all the parts are working in their best possible manner. If not, then replacement(s) might be required to ensure proper working of the valve.

Uses or Areas of Application

These engineered products are used in numerous areas. Some of the uses of a solenoid valve are as follows:

  1. Home Appliances: Be it a dishwasher or a washing machine, these appliances require solenoid valves to work efficiently.
  2. Gas Boilers: Another major use of these valves is in the gas boilers. In boilers, these valves work by controlling the flow of gas towards the burner.
  3. Automatic Irrigation Sprinkler Systems: Not just helping the homeowners of today, but these valves are quite popular in helping the agriculturists as well. The solenoid valves are used in the automatic irrigation sprinkler systems with an automatic controller or regulator.
  4. Dentistry: If you are wondering how these valves are helpful for the dentists, then don’t be amazed! The solenoid valves are used in the dentist chairs so as to regulate the air and water flow.
  5. Water Purifiers: One of the latest uses of Solenoid valves is in the water purifiers or RO water systems that are all the rage at present.
  6. Refrigeration Applications: Solenoid valves are also required in refrigeration applications to commence or restrict the flow in the refrigerant circuit, thereby automatically regulating the fluids in the system.

There are many uses of these excellent valves. However, what is important is that you choose a good supplier of such products, to ensure a long term and hassle free use for years to come. So, do a bit of research online and find a reliable manufacturer offering various types of valves.

ACTUATOR: A fluid-powered or electrically powered device that supplies force and motion to a VALVE CLOSURE MEMBER.

AIR SET: Also SUPPLY PRESSURE REGULATOR. A device used to reduce plant air supply to valve POSITIONERS and other control equipment. Common reduced air supply pressures are 20 and 35 psig.

AIR-TO-CLOSE: An increase in air pressure to the ACTUATOR is required to cause the valve to close. This is another way of saying the valve is Fail Open or Normally Open.

AIR-TO-OPEN: An increase in air pressure to the ACTUATOR is required to cause the valve to open. This is another way of saying the valve is FAIL CLOSED or NORMALLY CLOSED.

ANSI: An abbreviation for the American National Standards Institute.

ANTI-CAVITATION TRIM: A special trim used in CONTROL VALVES to stage the pressure drop through the valve, which will either prevent the CAVITATION from occurring or direct the bubbles that are formed to the center of the flow stream away from the valve BODY and TRIM. This is usually accomplished by causing the fluid to travel along a torturous path or through successively smaller orifices or a combination of both.

API: An abbreviation for the American Petroleum Institute.

ASME: An abbreviation for the American Society of Mechanical Engineers.

ASTM: An abbreviation for the American Society for Testing and Materials.

BALANCED TRIM: A trim arrangement that tends to equalize the pressure above and below the valve plug to minimize the net static and dynamic fluid flow forces acting along the axis of the stem of a GLOBE VALVE. Some regulators also use this design, particularly in high pressure service.

A butterfly valve is a type of quarter turn valve. A quarter turn valve can open or close whenever the handle is turned 90 degrees (a quarter of a turn). The main function of these valves is to control the flow of liquids through a section of pipe. Butterfly valves are mainly used in waste treatment systems. They are extremely durable and need minimal maintenance.

Butterfly valves operate like other quarter turn valves. Understanding the way a basic butterfly valve works is pretty simple. It can help you to learn more about the components of valves.

Butterfly valves are made of a number of components. The most important one is the metal disc. This metal disc is the one commonly referred to as the butterfly. The butterfly is mounted on a rod and when the valve is closed it blocks passage of fluid. When the valve is fully open, the metal disc or butterfly moves a quarter turn. The passageway is unrestricted allowing fluids or air to pass.

In essence, the movement of the disc will depend on whether the valve is open or closed either partially or completely. If the valve is opened partially, it means that the disc will not be rotated a full one quarter turn, thus it cannot provide unrestricted passage. This means that, smaller amounts of fluid or air will pass through. However, if the valve is opened completely, the disc will be rotated 90 degrees then larger amounts of air or fluid will pass through.

There are many other components that form the butterfly valve. They include the resilient seat, body, packing, a stem and an actuator. The resilient seat is mounted on the body of the butterfly valve in order to provide the proper seal. The packing provides an additional seal especially in case the resilient seat is damaged.

Butterfly valves are configured differently. There are some which operate manually whereas others operate electronically depending on the system. They also come in different styles. There are those which offer high performance in systems like large pump lines and front suctions.

Butterfly vales can also be used in automobile systems. For instance, you will find the butterfly valve inside the carburetor of a car. In this case, the valve is used to control the flow of air to the car’s engine. It can partially open and close to regulate the amount of air passing through.

Valve actuators are of various types namely electrically operated , pneumatically operated.

  1. Pneumatically operated actuators can be diaphragm operated for globe , gate valves.
  2. Pneumatic actuators can be quarter turn type for ball or butterfly valves.
  3. Pneumatic actuators can be cylinder operated for say Knife gate valves.
  4. Actuators are again single acting spring return type or double acting.
  5. Again electric actuators can be classified as on-off type or control ( modulating type).

On- off pneumatic actuators can be operated with solenoid valves . As you mention the fluid to be natural gas, you have to select solenoid valves which are intrinsically safe at the same time these valves may be placed at a safe distance from the valves and piping. These valves are again actuated by controllers( on -off , PID) connected to the level switches, pressure sensors or temp sensors as the case may be.

To control flow rates, you need to use a pneumatic control valve with a pneumatic positioner operating on (0.2-1 kg/cm2) with current to pressure convertor or an electroneumatic positioner ( 4-20mA control signal). These can be used to control flow rate or downstream pressure. Other elements required are pressure or flow sensors, PID controllers.

The control again depends on how the plant is operated ie DCS or PLC controlled.

If it a simple requirement then the actuatar can be made to operate on a system of limit switches. While selecting an actuator the fail safe mode ( in case of power, signal or air failure) should also be taken into consideration , which is specified by words like normally open or normally closed etc.

If you are in the valve world at all, you know that the plug valve oftentimes gets a bad rap. There are different reasons for this. One being that the maintenance for these valves is greater than that of other valves. They need to be lubricated while out in the field and more times than not, this is overlooked.

Secondly, due to the corrosiveness and high temperatures of the substances flowing through the plug valves, they tend to wear much quicker than that of some other valves. This means they require patching and maintenance on a regular basis.

Lastly, the plug valve is not the valve of choice when it comes to throttling. You will want a v port, butterfly or ball valve in those types of applications.

On a good note, the plug valve does not clog. And one of the most common uses for a plug valve would be in our homes or businesses where we utilize gas services. The brass, 2 port valve, which is used in gas lines, is conically shaped and its structure bares a handle. When the handle is turned to 90 degrees from the inlet and outlet ports of the valve, the valve flow is shut off. For the gas to flow though the pipes, the handle and plug would need to line up with the inlet and outlet ports of the valve body.

A straightforward description of a plug valve is best described as a rotational valve with a tapered disk resembling that of a plug.This plug or disk sits “long ways” in the valve and has a passageway bored through the center in order to accommodate passing air or fluids. This type of control for corrosive or high temperature air/liquids is economical and simple. With a 2 port valve there are two positions, open and shut. There are also multi-port valves available in the plug valve for different more complex type applications. In applications where there are more than 2 ports, you may have a need for a soft rubber overlay for a sure-tight shut off.Different types of seals are based upon gaskets. Some plug valves close against the gasket and some close directly on the seat.

Many oil field service companies, vacuuming devices and applications which are dealing with glassware stopcocks which create glass products, still utilize plug valves. It does indeed seem to be a dying breed of valves, but with the right material, the proper gasket/seat in a particular application, you may see that a plug valve can be successful for you…especially when expenses plays a factor in your decision.

To assist you better with your valve decision, make sure you contact your Valtorc sales specialist today. They can better educate you on what’s best for you and your application to obtain the maximum results of success.

We all know that valves are present in our everyday lives, but valves work a lot “behind the scenes”—controlling what might seem like the “uncontrollable”.  Without valves, we would have engineering issues on how to regulate and control steam, water, air, corrosive liquids, gases and other materials. You can already see WHY valves are important, but WHERE did valves originate, you ask? Good question…

Maybe ancient man watched the beaver as he built his dam across the river. In ancient times, man used tree trunks, thick grasses, rocks, boulders and branches to regulate water. The Egyptians and Greeks also designed valves to lead water to irrigate their crops and provide water to their villages. However, the Romans were the ones to truly develop their canal systems and had a higher engineered technology behind those systems. Due to various country invasions, one may be led to believe that the Romans stole some of their technologies that they utilized. Either way, the Romans took their technology findings on to further develop the bronze plug valve which enabled them to distribute water to buildings.

It was not until the Industrial Revolution that valves really evolved to the next level. Steam was the power required to reform and strengthen this era and replaced muscle or “horse” power. Valves along with the patented steam engine made it possible to pump water out of mines. During this time, the US was able to increasingly provide mining jobs to those out of work. Mining, agriculture, textile mills, manufacturing plants, steel production, transportation and many other industries were emerging quickly. The economy exhibited unprecedented growth and life was getting better financially for most. Water and steam along with the evolution of the valve, contributed highly to the success of the Industrial Revolution industries.

Today, there are diverse types of valves made of materials such as stainless steel, carbon steel, cast iron, bronze, brass, PVC, CPVC and other alloy materials. Valves can be very small in size or up to 102 tons, which is the largest valve in the world! (See http://www.valveworldexpo.com/cipp/md_valve/custom/pub/content,oid,1943/lang,2/ticket,g_u_e_s_t/local_lang,2)  The application determines what type of valve you would need in order for your line to be successful. When ordering your valves, you want to ensure that you work with a reputable company such as Valtorc International. They will want to know all aspects of your application to determine which type of valve(s) would be best suited for your needs. Here is something else to think about—ask the supplier/manufacturer if their products are made in the US.  Let’s strengthen our economy and keep sales in our country when we can!
