CG5V-10 Series

CG5V-***, 20 series: relief valve with solenoid operated pilot valve for loading/unloading

These two-stage valves are used to limit or control pressure by directing up to the total system fluid flow to reservoir when system pressure reaches the setting of the valve. System actuators are thus protected against overload.

Each relief valve incorporates a vent port that can be connected to a separate pilot control valve to remotely control or unload system pressure.

Basic Characteristics

Maximum pressure . . . . . . . . . . 350 bar (5000 psi)

Maximum flow . . . . . . . . . . . . . 400 L/min (106 USgpm)

Mounting face to ISO 6264:

CG*V-6 valves . . . . . . . . . . . . AR-06-2-A

CG*V-8 valves . . . . . . . . . . . AS-08-2-A

Features and Benefits

• Close matching to application requirements from choice of four adjustment control ranges covering 3 to 350 bar (44 to 5000 psi).
• Electrical on/off load from solenoid controlled models.
• Remote parallel control by other pilot valves connected to “vent” port.
• High machine productivity resulting from full system flow being available for work output until system pressure is very close to valve setting.
• Pressure override optimized without detriment to other performance parameters.
• Excellent repeatability and stable performance from cartridge-type design of mainstage parts.
• Low off-load power wastage.
• International mounting interfaces.
• Low installed cost and space requirement from high power/size ratios (more than double that of many conventional designs).
