Manual Plastic Butterfly Valves

Type-55 Butterfly Valve (2"- 10")

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.
