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_p.pngElectric as well as pneumatic actuators are quite well known for their varied uses. In case you are confused as to which type of actuator out of these two will suit your needs, then we are there to help you.

An electric actuator is the one which makes use of electrical energy to produce mechanical energy. While, a pneumatic actuator, is an air operated actuator, which converts air pressure into mechanical force to operate the valve.

Read on to find the basic points of difference between an electric and pneumatic actuator.

  1. High force & speed – When it comes to the force and speed of the pneumatic actuators, then it is worthwhile to note that they offer more force and speed per unit size than the electric actuators. One can easily adjust the force and speed on the pneumatic actuators. Thus, for those of you who need to control and regulate the force and speed in the system, should go for pneumatic actuators without any doubt.
  2. Component cost – If you are considerate about the component costs of pneumatic actuators, then you would be glad to know that they are low. The electric actuators come with a hefty component costs, and are thus often avoided by the users.
  3. Operating cost – Regardless of the low component costs of pneumatic actuators, their maintenance and operating costs are quite high as compared to the electric actuators. These costs consist of replacement costs of the cylinders, electricity charges, airline installation and maintenance, etc.
  4. Heating – Owing to their perfect design that resists overheating, the pneumatic actuators are favored by many. In contrast, the electric actuators can tend to overheat. So, if you want an actuator that does not overheat easily, then go for the pneumatic one.
  5. Moisture – Another point of difference between these two types of actuators is their resistance to moisture. While the pneumatic actuators are insensitive to wet environment or moisture, the electric actuators need to keep well away from moisture.
  6. Stalling – When it comes to the pneumatic actuators, they can be stalled easily. But, the electric ones cannot be stalled during their operation or use.
  7. Torque to weight ratio – The pneumatic actuators have a high torque to weight ratio as compared to the electric actuators.

Thus, keep all these points in mind and go for that actuator that suits your requirements the best. After all, investing in these tools is not an easy decision to make! So, consider all the points of differences and opt for the right actuator.

b2ap3_thumbnail_actuated-valve-blog.pngValves are one of those critical inventions that go unnoticed by many. They play an important role in our world by controlling, regulating, guiding and directing the flow of assorted types of liquids, gases, steam or flowing materials such as mill, grain, etc.

Valves are made of steel, iron, steel, bronze or PVC and can handle high temperatures and pressure points. In certain applications, the velocity, which is controlled by the valve, is vital in the success of the system in which it is applied and can be manually controlled or automated. In every industry, there are various types of valves including ball, butterfly, v-port, solenoid, sanitary, knife gate, plug and many more. The following is just a few examples of where valves are critical in a particular application: sewage/waste water plant, dams that controls a body of water, valves in your vehicle that control gas flow or oil flow to your engine and oil and gas refinery companies.

Oftentimes, an actuator is attached to the valve to administer pressure control and flow control in applications where it is crucial that the actual value be the same as the set point value. This motor box is operated by pneumatic pressure or an electric current. It then changes this energy into motion which changes or moves the valve positioning in order to keep to the set point that was entered into the actuator by the operator.
