A wide range of check valves specifically designed for high pressure and high temperature applications.
Main Features
Available in swing check, tilting disc and piston check (Y andT pattern design).
Swing check valves can fit on both horizontal and vertical (up-flow) piping.
Tilting disc check valves are designed to prevent the disc slamming and to ensure, at the same time, a quick closing service.
Lift check valves (Y and T patterns) are designed to be installed on horizontal piping.
Seat is welded in
Available options: side mounted counterweight, side mounted hydraulic damper and disc anti-rotation device
