The se
7、condary pressure isset by the pressure adjustment element (4).At rest, the valve is normally open and the pressure fluid can flowunhindered from port P to port A. The pressure in port A is at thesame time,via the control line (6),present at the spool area oppositeto the compression spring (3).When t
8、he pressure in port A exceedsthe pressure level set at compression spring (3),the control spool (2)moves into the control position and holds the set pressure in port Aconstant.The control and pilot oil are taken from port A via control line (6).If the pressure in port A increases due to external for
9、ces on theactuator, then the control spool (2) moves still further towards thecompression spring (3).This causes a flow path to be opened at portA via control land (8) onthe control spool (2) to the tank. Sufficient pressure fluid then flowsto tank to prevent any further rise in pressure.The spring
10、chamber (7) is always drained to tank externally via portT(Y).For free return flow,from portA to port P,an optional check valve (5)can be fitted.A pressure gauge port (1),permits the secondary pressue at the valveto be monitored.Version YInternal pilot oil supplyexternal pilot oil drainwith check va
