Product Description
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. 
▪KARFAR lined ball type check valve H40 do not have a spring to assist closing, which limit their use to vertical lines with upwards forward flow. The solid PTFE ball inside body chamber guarantees that ball rolls into the seat due to gravitation. Self-cleaning are achieved due to non stop rotation of the ball and prevents solid particles precipitation. 

KARFAR lined sight-glass ball type check valve SH40 is for safe flow control, with visual flow observation. 
▪This valve can be used in any corrosive medium in addition to the "molten alkali metals and fluorine elements". It is an ideal product used in chlor-alkali, industrial in organic chemicals, metal and mining, nitrogen and phosphatic fertilizers, petroleum refining, pharmaceutical etc. 
▪Lining material: PFA, FEP, PO etc.
▪KARFAR lined check valves are available as per the needs of applications in additional sizes and other than standard materials.
