For products inthis catalog the recommended levelsare:Up to 210 bar (3000 psi)19/17/14.. Mounting PressureInlet ports210 bar (3000 psi).. Drain ports1,7 bar (25 psi).. Note: Drain ports must be piped direct toreservoir. Any back Pressure at this port willincrease the effective Pressure setting of thevalve by the same Flow Rate and Min.

4 If max. inlet Pressure is required with min. rated reduced Pressure , consult your Vickers data giving max. flow for -*B- Pressure SettingFor proper functioning the inlet pressuremust be maintained at least 10 bar (150 psi) above the setting of the reducedoutlet Pressure ControlReduced Pressure may be adjustedremotely by connecting the remote controlconnection to the inlet port of a C-175relief valve (catalog 411) or a CGR-02relief valve (catalog 409). Pressure setting of the X(C)T valve mustbe higher than that of the remote FluidsX(C)T Valves are suitable for use withhydraulic oils, oil-in-water emulsions andwater fitted with special seals (specify F3 in model code ) these Valves aresuitable for use with phosphate esters(not alkyl-based).The extreme operating range is from 500to 13 cSt (2270 to 70 SUS) but therecommended running range is 54 to 13 cSt (245 to 70 SUS).
