CGR Series

CGR-02 Relief Valves

eaton CGR Series

CGR-02 Relief Valve Subplate mounted Remote Control

Typical application is as a remote control device for balanced piston type relief valves. The CGR-02 is not intended for use as a relief valve by itself. The valve is normally used to provide adjustment of system pressure from a convenient or remote location.

Pressure Range

The available pressure ranges for this valve are from 4,5 to 70 bar (65 to 1000 psi), from 4,5 to 140 bar (65 to 2000 psi), and from 4,5 to 210 bar (65 to 3000 psi). Therefore, the main system relief valve being controlled by the CGR-02 should be selected according to the maximum pressure required in the system. Check the model code for the main system relief valve.

Pressure Adjustment

Pressure can be adjusted by loosening a jam nut and turning an adjustment screw or optional adjustment knob. Turning clockwise increases pressure, and turning counterclockwise decreases pressure. The maximum pressure that can be attained by turning the adjusting screw is set at the factory to the value specified in the model code.

Ratings

The CGR-02 is rated for a maximum pressure of 210 bar (3000 psi).

Basic Characteristics

Operating Data

Maximum Pressure

70, 140 or 210 bar (1000, 2000 or 3000 psi) according to adjustment range.

Maximum Flow Rate

All models 4,1 L/min (15.5 USgpm)

Control Data

The pressure is adjusted by slackening the locknut and turning the adjusting device in a clockwise direction to increase pressure and counterclockwise to decrease pressure. Re-tighten locknut after setting the pressure.

The outlet port should be piped directly to tank at atmospheric pressure. Any pressure at the drain port is additive to the pressure setting of the valve.

Hydraulic Fluids

All valves can be used with antiwear hydraulic oils, water-in-oil emulsions and water glycols.

Add prefix “F3” to model designation when phosphate ester (except alkyl-based) or chlorinated hydrocarbons are to be used.

Viscosities can range between 860 and 13 cSt (4000 and 70 SUS) but the recommended running range is from 54 to 13 cSt (245 to 70 SUS).
