General Description
3 Way, Normally Closed, Proportional Flow Regulator
Valve. Pressure Compensated. For additional informa-
tion see Technical Tips on pages PV1-PV6.
Features
•
Analog proportional pressure compensated flow control
valve regulates 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.
