PFA/FEP Ball Check Valves

PFA/FEP Lined Ball Check Valves are specially designed to handle corrosive and aggressive fluids in chemical and process industries. These valves feature a fully fluoropolymer-lined interior (PFA or FEP), ensuring maximum resistance against acids, alkalis, and solvents.
The valve operates automatically — when fluid flows in the forward direction, the PTFE or FEP-lined ball is lifted to allow flow. When flow stops or reverses, the ball settles back, sealing the flow path and preventing reverse flow.
These valves are ideal for vertical or horizontal installations and offer maintenance-free operation with long service life, even in highly corrosive environments.
