High Pressure Check and Relief/Check Valves

custom check valve

These inline valves allow free flow in only one direction, prevent backflow, and meet the industry's need for higher operating pressures. They also are used for relief and by-pass functions; however, they should not be used as safety relief valves. Kepner's Flexible Seal Seat™ combines metal-to-metal contact with a resilient seal seat ensuring bubble-tight shutoff of liquid or gas. This is an ideal choice for applications that require positive leak-tight sealing and long service life at pressures to 6000 PSI. Standard and specialty valves handle a wide variety of applications.

Features and Benefits:

  • Flexible Seal Seat™ for zero leak (bubble-tight) sealing to 6000 PSI
  • O-Ring seal positively secured
  • Non-pressurized threads
  • Poppet stop inside valve body prevents spring from bottoming out
  • Generous flow passages allow full flow with minimal pressure drop
