Type-55 Butterfly Valve

Type-55 Butterfly Valve Type-55 butterfly valves are quarter turn plastic valves with equal percentage type flow characteristics. They provide moderate flow control and therefore can be used for both on/off and modulating service. The Type-55 butterfly valve features an epoxy powder coated ductile cast iron body with PTFE disc and Liner. The Type-55 is designed for use in applications where conventional rubber liners and thermoplastic discs would fail. Can be pneumatically or electrically actuated. Ideal Applications Include: Isolation valves, control valves, chemical processing, mining Features & Benefits: Highly corrosion resistant PTFE disc and seat Epoxy powder coated ductile iron body for corrosive atmosphere or environments Strong but thin disc with high Cv value Stainless steel stem has full engagement over the entire length of the disc and is a nonwetted part, totally isolated from the media Only PTFE disc and PTFE seat are wetted parts Bubble-tight shut-off Rated for full vacuum service Locking device 21 position throttle plate for lever handle style Asahi Part Numbers: 1717020, 1717030, 1717040, 1717050, 1719020, 1719030, 1719040, 1719050, 1719060, 1719080, 1719100
