A range of pressure seal Check Valves designed according to ASME B16.34.
Available in Swing Check, Tilting disc and Piston Check (Y and T pattern design)
All range is offered in all the material stated in the ASTM specifications, and designed to always guarantee the maximum safety and flow efficiency.
End to end dimensions as per ASME B16.10
Swing and tilting disk check valves can be installed on both horizontal and vertical (up-flow) piping.
Stop check valves (Y and T patterns) are designed to be installed on horizontal piping.
Tilting disc check valves are designed utilizing triple offset seat geometry to prevent the disc slamming, stable disk operation and to ensure, at the same time, a quick closing service.
Tilting disc seat is manufactured directly in the body therefore removal of seat/body welding avoids distortion of seat face.
