KCG-6/8

KCG-6/8 Series Proportional Pressure Relief Valves

eaton kcg

These two-stage pressure relief valves offer extensive application possibilities through their ability to control the pressure setting in proportion to an applied electrical input (up to a pressure limit which is manually adjustable and lockable).

Two model types are available

KCG-6/8

The 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. The proportional pilot control stage is a Vickers type KCG-3 valve.

KACG-3

The addition of an integral amplifier allows the pressure to be controlled from a 0 to +10V, or 0 to –10V command signal range. The amplifier is mounted in a robust metal housing and electrical connections are via an industry standard 7-pin plug. Factory-set adjustments ensure high reproducibility valve -to-valve.

Basic Characteristics

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

Features and Benefits

  • With or without integrated electronics.
  • Remote electrical proportional control of pressure from a choice of five pressure ranges per valve size.
  • Excellent repeatability and stable performance results from cartridge design of mainstage elements.
  • Low installed cost and space requirement from high power/size ratios (more than double that of many conventional designs).
