Product Description

Introduction

Pneumatic PTFE lined butterfly valve regulates flow or cuts off media by rotating disc(usually less than 90°).No self-locking function with disc or rod,install worm reducer on stem for disc location.Use FEP(F46),PCTFE(F3) lining to protect valve body from corrosion of media.

Butterfly valves for industries are manufactured with WCB for valve body,rubber ring replaced by metal ring for disc seal ring,and suitable for high temperature,high-pressure and large-bore applications.Large pneumatic butterfly valves are manufactured by steel plate-welded and mainly used for smoke and gas pipelines flow with high temperature media.

Features and Application

With quick action,low torque,good sealing and long service time characteristics and used to cutting off and regulating,pneumatic PTFE lined butterfly valve is suitable for serious corrosion media(fluid,gas,steam).No limit of installation and easy for maintenance.Bidirection sealing and sealing elements changing is available.

Pneumatic actuator

AT-type pneumatic actuator includes double-acting and single-acting(spring return),gear driving with higher safety.AW type pneumatic actuator includes double-acting and single-acting with proper structure,lager output torque and fork-type driving.

Aluminum gold material for cylinder(light weight)

Handwheel installation at the bottom or roof is available.Optional electric actuator feedback signal instructions and all kinds of accessories for automatic operation.
