Product Description
The Swing Type & Lift Type Check Valve is engineered to prevent reverse flow
in high-pressure industrial piping systems while ensuring reliable and maintenance-free operation.
Manufactured with a robust bolted cover and straight body design, these cast steel non-return
valves are available with renewable seats and premium trim materials for extended service life.
Swing Check Valves are suitable for horizontal and vertical upward flow, while Lift Check Valves
are designed for horizontal installations. Optional bypass arrangements and Stellite hard-faced
seating are available for severe service applications.
