Double Eccentric High Perormance Butterfly Valves Series 1200

Features:

• Click here to download the Butterfly Valve Installation, Operation and Maintenance Manual
• The Butterfly Valves top flange is drilled as per EN ISO 5211 to accommodate direct mounting of a wide range of actuators.
• One-piece wafer body style or full lug style for dead end service. Both Butterfly Valve body styles offer bidirectional sealing as standard in conformance with full ASME class 150 and class 300 rating.
• Butterfly Valve Pins are offset from the center of the stem which places them in compression rather than shear thus eliminating potential for failure. The pins are precision fit and wedge types which provide positive mechanical attachment of disc to stem.
• The disc stop is a machined position stop on the body that locates the disc in the seat to achieve maximum seat and seal life. The disc stop is designed to prevent disc from rotating in to the wrong direction and minimizing possible seat damage.
• The unique Butterfly Valves seat design utilizes a flexible lip seal concept When the disc closes, this action causes a slight deflection in the seat, energizing the seat.

High Flow Resilient Seated Butterfly Valves Series 1300

Features:

• Click here to download the Butterfly Valve Installation, Operation and Maintenance Manual
• Four flange locating ribs for sizes up to 12” and four flange locating holes from size 14” to 24” for easy alignment  of  valve  during installation. They meet ANSI #125 /150  or  other  world  drilling standards.
• Unique stem retention system to provide blow-out proof stem and easy assembly and  disassembly of the Butterfly Valve.
• Heavy  duty  one-piece  body Butterfly Valve. Standard coating is two coats of hard, zinc-rich epoxy for excellent corrosion resistance.
• Precision machined radius on the upper and lower disc hubs is pressed against upper and lower seat  sealing  faces  for  achieving primary sealing   between disc and seat.
• Positive disc stem engagement by a precision machined square drive, eliminating potential leak path and failure of stem joint.
• High flow disc Butterfly Valve design provides a streamlined flow passage, enhanced flow characteristics and reduced  resistance  to  flow especially for control applications.

Stainless Steel Series 1400 Butterfly Valves
