Split Flange Check and Relief/Check Valves

custom check valve

The flanged, spring-operated, poppet valves allow free flow in only one direction and prevent backflow. They are also used for relief and by-pass functions; however, they should not be used as safety valves. The valves can be direct mounted to pumps, motors, and other such applications where threaded end connections are impractical or inconvenient. Kepner's Flexible Seal Seat™ combines metal-to-metal contact with a resilient seal seat ensuring dependable bubble-tight shutoff of liquid or gas, as well as surge protection and long service life. Standard and specialty valve designs handle a wide variety of applications.

Features and Benefits:

  • Flexible Seal Seat™ for zero leak (bubble-tight) seal at low and high pressures
  • SAE 4-bolt, Code 61 mounting; easy installation and maintenance
  • O-Ring seal positively secured
  • Poppet stop inside valve body prevents spring from bottoming out
  • Generous flow passages allow full flow with minimal pressure drop
