Pressure Seal Check Valve

GMK Pressure Seal Check Valve is a selection of valves that have been developed in accordance with ASME standard B16.34. It Can be purchased in Swing Check, Piston Check, and Tilting Disc varieties (Y and T pattern design). It was developed to always provide the highest possible level of flow efficiency and safety. The dimensions are from end to end by ASME B16.10. Swing check valves and tilting disc check valves are both suitable for installation on horizontal as well as vertical (upflow) pipes. Stop check valves, also known as Y and T designs, were developed specifically for use on horizontal pipework.

GMK tilting disc check valves are built with triple offset seat geometry to prevent the disc from slamming, maintain stable disc operation, and ensure speedy closure service at the same time. This is done to prevent the disc from slamming. Since the tilting disc seat is produced directly in the body, the elimination of seat/body welding helps to prevent the face of the seat from becoming misshapen.


  • The potential of pin seal leakage is removed, and in-line maintenance is made possible since the hinge pin is not exposed to the outside.
  • All of the mobile components of the cage are linked to the carrier and may be removed quickly and simply for maintenance.
  • To provide optimal erosion resistance and extended service life, the forged seat/disc is made of CoCr alloy that has been honed and lapped to a mirror finish. It’s a sealed weld to the main structure.
  • To ensure a secure shutdown, the disc may revolve inwards to a certain degree. It comes to a standstill when opened all the way.
  • Hinge pin bearings made of CoCr alloy.
  • Simple counter service. It’s simple to get to all the component components for servicing. Seat fronts are remappable.
  • Hat with a forged crown.
