PSV7-10 - Pressure Sequence Valve
Spool, direct acting, normally closed, internal pilot, external drain
23 L/min (6 USgpm) • 210 bar (3000 psi)
Operation
As with the direct acting relief
valves, when the pressure
exceeds the spring force, the
spool moves back, opening the
inlet to outlet.
Features
Stable, quiet operation.
Cartridge construction
gives maximum flexibility
in mounting. Offering good
repeatability and reseat.
