When liquid flows through the valve, the ball is forced into the branch of the valve allowing full fluid flow. When the liquid stops, equalizing the pressure, the ball drops back into the seat, preventing backflow. Should reverse flow occur, the differential pressure will cause the ball to seal firmly against the seat preventing leakage.

Features:
  • Maximum operating pressure: 250 PSI
  • Maximum operating temperature: 250ºF
  • Two piece construction for easier alignment during installation
  • Various end configurations available: clamp, weld, I-line, Q-line, bevel seat and John Perry
  • Polished ID and OD to 3A standards
  • All metal contact surfaces of 316L stainless steel construction
  • Air blow check valve can be added (see air blow for sizing)
  • PTFE ball
