Working Principle
Generally check valve is automatically working, under the pressure function of one direction flow, the disc open, while when the liquid back flows, the valve will cut flow. PTFE/PFA Lined check valves only allow one way flow direction and prevent the back-flow of liquids in pipeline. The solid PTFE ball at valve body lining guarantees that ball rolls into the seat due to gravitation.
