    ISO 6284 Size 6/8 (Pressure Reducing) Proportional Valves

    ISO 6284 Size 6/8 (Pressure Reducing) Proportional Valves

    Proportional Pressure Reducing Valves


    K(A)X(C)G-6/8, 1* Series

    Basic Characteristics
    • Max. inlet pressure 350 bar (5000 psi).
    • Max. reduced pressure 330 bar (4750 psi)
    • Max. flow rate 300 L/min (80 USgpm)

    These two-stage pressure reducing valves (based on Vickers type X(C)G2V valves, featured in catalog 2321) incorporate an electro-hydraulic proportional pressure pilot stage (Vickers type KCG-3 valve, described in catalog 2162) 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.

    Design Features

    A maximum outlet pressure to suit the application requirements is preset by the manual adjustment. Below this maximum setting, the outlet pressure is controlled by the solenoid operated proportional pilot valve, according to the current applied to the solenoid.

    The “normally open” condition of the mainstage allows full flow from inlet to outlet port until the required reduced pressure is reached, whereupon the mainstage closes, or reduces the flow sufficient only to maintain the required outlet pressure.

    High valve response ensures that the reduced outlet pressure is unaffected by inlet pressure peaks. Excess build-up of outlet pressure (during long holding periods, or flow back from an actuator reacting to an overload) is prevented by the small check valve in the mainstage spool, allowing fluid to bleed-off across the pilot stage

    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).
