Product Description

General

FREE-VALVE Plastic floating ball type check valve is straight type integral body design and manufactured in uni-directional body design.The valve uses PTFE as the rolling valve ball, the valve can be opened or closed by ball rolling up and down in the slide of the body chamber body under the medium acting.Under normal flow the valves solid PTFE ball is pushed away from it's seat and fluid flows through the valve,  in a backwards flow condition the ball is pushed firmly back into it's seat and prevents flow through the valve stopping process, etc.

 

Features

 

1. Good sealing performance, noiseless closing.
2. Vertical installation is acceptable.
3. All the parts that will touch medium is made of plastic.
4. One Pcs body type ,avoid any outside leakage to the atmosphere.
5. Lead rail design make the floating ball seal with body better.
6. Working temperature:

FRPP -14ºC~ +90ºC,UPVC -10ºC~ +60ºC,PVDF -40ºC~ +150ºC,CPVC -20ºC~ +95ºC
