1 TYPICAL PERFORMANCE SPECIFICATIONS DESCRIPTION These proportional valves are direct operated pressure reducing valves. They can be used to control pressure in parts of a circuit. This valve incorporates a pressure control spool with a pressure sensing piston to sense downstream pressure. The single solenoid version, code, will allow fluid flow from P port to port when an electrical signal is applied. If the signal is decreased to zero, P port will be blocked and port opened to the tank port. The code A version will allow flow from P to A. The double solenoid version will allow flow from P to A (or P to ) when the signal is applied to the proper solenoid. A and ports are used alternately for pressure reduction in the respective port. P and T ports are common.
