Check Valves | Compact

Space-saving Compact Check Valves’ design allows product flow in one direction while preventing flow in the opposite direction. Fully automatic, the line pressure keeps the Valve plunger open. When line pressure drops or there is reverse flow the spring will cause the plunger to firmly seat, returning the Valve to the closed position. The angled design of the plunger prevents leakage in low pressure systems. Precision machined Valves manufactured by Steel & O’Brien are available in a variety of end configurations. The Check Valve sizes range from 1/2″ to 4″.

  • Strong performance in high or low pressure systems
  • All wetted surfaces polished to >32Ra
  • Easily field serviceable, no special tools required
  • Assembled with EPDM o-ring seal
  • All stainless steel components (except clamp and spring) are manufactured at Steel & O’Brien
