  • 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.
