Product Description

FREE-VALVE Plastic Wafer Swing Flap Non Return Check Valves  are installed in the piping system, their main function is to prevent medium from flowing backwards, the valves are swing type ,and comes with a short pattern sandwich type flangeless wafer body conforming to the GB/T12221 face to face dimensions,the valve performs the same with Swing Check Valve with much less cost and has a simple but reliable and robust construction.

Features

1. The eccentric mounted hinge pin in combination with the disc seat guarantees a positive shut off of the returning medium.
2. Seat Ring is replaceable type.
3. Tightening torque to be applied on the companion flange bolting is lower due to face sealing O-rings.
4. Short Face-to-face.
5. Self centering in pipeline due to controlled outside diameter, enables easy installation.
6. The valves are suitable for mounting between weld neck or slip on type companion flanges of different standards.
7. Working temperature:

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