1 Relief ValvesRemote Controls, Relief and Sequence Valves , and Single andMultiple Pressure Solenoid and Air Operated Relief ValvesVickers Pressure Relief2 IntroductionRemote ControlsSmall, easily installed remote pressurecontrol Valves make it possible to controla balanced piston Pressure Relief valvefrom a more convenient and SequenceValvesPressure Relief Valves mount betweenthe pump and valve system to protectagainst overloads. A suitable pilot valvemay be used to vent the balancedpiston Relief valve when the system doesnot require power. This venting unloadsthe pump through the Relief valve at lowpressure, avoiding energy waste andreducing operating sensitive adjustment mechanismallows the setting of the Pressure in fineincrements over a wide range up tothe maximum rating of the Relief Valves at the controlconsole or other remote location, andelimination of separately mountedhydraulic remote controls and relatedconnecting piping, result in lowerinstalled cost.

The pressuresetting of the valve is approximatelyproportional to input current; increasingcurrent provides increasing OperationA manual override adjustment of theCGE-06/10 operates over the full pressurerange and should be set just above themaximum Pressure to be controlledelectrically. For example, the overrideshould be set at 2200 psi when maximumelectrically controlled Pressure is 2000 override adjustment can also beused for complete manual operation ofthe valve during set up and troubleshootingby isolating the pilot head section fromthe manual override section.

If tank lineback Pressure exceeds system pressureby 7 bar (100 psi) a malfunction mayoccur. Any Pressure in the tank line is anadditive when the valve is controlled bythe manually adjusted (non-electrical) Drain ConnectionDrain line must be full size unrestrictedand connected directly to reservoir sothat it terminates below reservoir fluidlevel. No other lines are to be connectedto this drain line. Pressure in this line(taken at the valve) not to exceed 1 bar(15 psi).

The CGR-02 is notintended for use as a Relief valve byitself.

10 The valve is normally used toprovide adjustment of system pressurefrom a convenient or remote RangeThe available Pressure ranges for thisvalve are from 4,5 to 70 bar (65 to 1000psi), from 4,5 to 140 bar (65 to 2000psi), and from 4,5 to 210 bar (65 to 3000psi). Therefore, the main system reliefvalve being controlled by the CGR-02should be selected according to themaximum Pressure required in thesystem. Check the model code for themain system Relief AdjustmentPressure can be adjusted by looseninga jam nut and turning an adjustmentscrew or optional adjustment clockwise increases Pressure ,and turning counterclockwise decreasespressure. The maximum Pressure thatcan be attained by turning the adjustingscrew is set at the factory to the valuespecified in the model SymbolRatingsThe CGR-02 is rated for a maximumpressure of 210 bar (3000 psi).
