Product Description

           PTFE Seat Wafer Ductile Iron Single Acting Air Actuator Butterfly Valve



Product profile:

Category : Pneumatic Butterfly Valve

Product Name: Fluorine Anti-corrosive Pneumatic Butterfly Valve

Product introduction:This butterfly valve adopts polytetrafluoroethylene (PTFE) as anti-corrosion lining material which has very superior anti-corrosion and abrasion resistance. The unique structure of upper lip type elastic seal lining well extends service life of the product.
Pneumatic piston actuator is divided into spring-type and spring-free type. When the valve is required to be fully opened or closed under fault it is equipped with spring type (by restoring tension of spring). When it is required to maintain position under fault it is equipped with no spring type.

*Small volume and light weight easy to disassemble and maintain and can be installed in any position
*Linearity flow characteristics,Excellent regulated performance
*Simple and compact structure
