KX(C)G-6/8 Proportional Pressure Reducing Valves

The KX(C)G-6/8 two-stage pressure reducing valves incorporate an electro-hydraulic proportional pressure pilot stage valve by which the reduced pressure setting is adjustable in response to an electrical input. Each model (in two sizes, with optional free reverse flow check valve) responds to variations of current input to its solenoid, for which separate Vickers drive amplifiers, with PWM output stage and output current control, are available.

Basic Characteristics

Max. inlet pressure 350 bar (5000 psi)

Max. reduced pressure 330 bar (4750 psi)

Max. flow rate 300 L/min (80 USgpm)

Mounting face to ISO 5781 (B port high pressure inlet):

• For KX(C)G-6 AG-06-2-A
• For KX(C)G-8 AH-08-2-A

Features and Benefits

• Remote electrical proportional control of reduced pressure from a choice of five pressure ranges per valve size.
• Excellent repeatability and stable performance results from cartridge design of mainstage parts.
• Low installed cost and space requirement from high power/size ratios (more than double that of many conventional designs).
