3 General Description and Operating Principle DESCRIPTION: 5 Made in Luxembourg Moog Hydrolux s DPCMEE series differential proportional flow control valves are used to regulate flow from port to port. This valve uses a self-regulating hydraulic design for control of flow rate by a current-controlled PWM signal.this screw-in cartridge type valve is designed to fit in SE style cavity with UN thread for use in manifolds. It can also be used in conjunction with 2- or 3- way pressure compensators as a 2- or 3- way pressure compensated flow control valve. OPERTING PRINCIPLE: Y (Tank Port) This valve is in a normally closed condition. In the closed condition the pressure of the fluid at the port is sensed through the orifice (2) and acts on the main spool (). Since the pilot spool (4) is a pressure balanced design, the main spool is held closed due to the hydraulic pressure and the spring (3) force.when a current signal is applied to the valve, the proportional solenoid (5) extends. The force of the solenoid (5), which is directly proportional to the applied signal, pushes the pilot spool (4) downwards. t this time the pilot spool (4) connects the pilot side flow to the tank port internally, thus creating a pressure drop across the orifice (2).This will allow the main spool to move upwards, allowing flow from port to port.s the main spool () opens, the forces become unbalanced between the spring (3) and solenoid (5) acting on the pilot spool (4). t which time this force balance is reestablished, the main spool () stops moving.this allows the valve to be used for proportionally controlling the flow by steplessly varying the input current signal. 4
