3 Way Normally ClosedPressure Compensated

Analog Proportional Pressure Compensated Flow Control Valveregulates flow proportionally to the input solenoid current. One piece cartridge housing ensures internal concentricity. Coil: Waterproof, hermetically sealed, requires no O-rings;Symmetrical coil can be reversed without affecting performance.

Nonmagnetic spool and housing assembly. Factory-adjusted low variation option (Model “L”) is available for applicationswhere low variation of flow from valve to valve is essential at a given current.

OPERA TION 1 , and bypasses the remainingflow to the port

3

The solenoid force is balanced against a precision bias spring. The valve establishes regulated flow to port 3 . The regulated flow is virtually independent of pressurefluctuation at any of 3 ports:
