Flowserve – Piston (Lift) Check Valves – Univalve

Flowserve – Piston (Lift) Check Valves – Univalve

  • Increased uptime from the use of anti-thrust rings in the body-guided disc, which eliminates misalignment and galling
  • Greater process control due to the integral hard-surfaced seat, which allows positive shutoff and seat life
  • Enhanced service integrity through an optimum flow shape that minimizes flow direction changes and pressure drops
  • Lower operating costs enabled by a die-formed, flexible graphite gasket seated to a prescribed bonnet torque that provides a reliable seal
  • ASME B16.34
  • ASME Section III
