Product Description
Anti Corrosive Lined Lift Type Check Valve
Model No. GLH41 / GLH42 
Anti Corrosive Lined Lift Type Check Valve (FEP / PFA / GXPO)


Size: DN15 ~ DN350
Lining material available: PFA, FEP, PO etc.


The KARFAR Lined check valve only allows medium flows in one direction, and prevent fluid flow backwards. The valve automatically works under hydraulic pressure, When there is back flow, the PTFE ball inside the body will rest on the seat by backflow pressure and its own weight and cut off back flow.

 Lined check valves has many types, all of which fulfill the same basic purpose, namely to allow fluid move forward, but to stop flow backwards. They prevent the back-flow of liquids in pipelines, prevent siphoning of pumps and eliminates pump impeller rotation in opposite direction due to back-flowing media. Generally check valvev can work automatically . Under the pressure forceof one direction flow, the disc opens, while when the liquid backflows, the valve will shut off.
