Polymer butterfly valve

A polymer butterfly valve uses a rotating disc in the flow path and is identified by its body form and polymer product category. Wafer or lug style, disc and liner materials, connection, actuator, and rating are not defined by the name. Material compatibility, seating torque, and actual model data require verification.

Application and duty

Isolation or control with verified butterfly geometry and polymer materials

TECHNICAL REFERENCE

Selection summary

Corrosion-resistant systems for water, chemicals and light-duty services

Polymer type, joining method, temperature-derated pressure, thermal expansion and chemical compatibility must be considered as a complete system.
