PTFE Seat Wafer Ductile Iron Single Acting Air Actuator Butterfly
Valve
Product Description:
Wafer Ductile Iron Single Acting Air Actuator Butterfly
Valve/Anti-corrosive/PTFE Seat
Description:
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.
Features:
*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
