Data is typical with oil at 22 cSt (106 SUS) and at 50 C (122 F)

Maximum pressures:
Ports P and X
Port T:
CG2V valves, 10 series
CG5V valves, 20 series
For relief valves this is normally connected directly to reservoir because back pressure here adds to the effective setting of the valve.

350 bar (5000 psi)

350 bar (5000 psi)
100 bar (1500 psi)
CG5V, 20 series valves are designed to satisfy the needs of most applications. Consult your Vickers representative about an alternative
model if:
a) Valves are required to remain pressurized for long periods without frequent switching, and/or
b) Back pressure on port T is required to rise above 100 bar (1500 psi).
