Check Valves Flange SAE

Check valve series SAE

Pressure [bar]


Flow rate [l/min]


Check valves for SAE flange ports are characterized by very high load capacity and very small pressure rise. The valve can be used without modification on both 3000 psi (210 bar) and 6000 psi (420 bar) SAE flange ports. The no-flow direction can be reversed by inverting the valve. The valve design is based on a guided poppet that is hardened and ground. In the no-flow direction, the valve closes. The valve can be used for pressure relief in the opening direction, but only to a limited extent (consult Bucher Hydraulics for such applications). Seal plates and insert plates are available as required. The valve is available in nominal sizes ¾“, 1“, 1¼“, 1½“ and 2“.

  • Compact construction
  • No-flow direction can be reversed
  • The same valve body is used for 3000 psi and 6000 psi ports
