Rexroth Direction Valve 4WMM10D31 F Blue/White Flexible Operation High Flow Rate

Product Specification

Description:

The Rexroth Direction Valve 4WMM10D31 F is a 4/3 or 4/2 directional valve element with a solenoid-operated directional spool. In the de-energized state, the control spool is held in the neutral position by a reset spring. A spool position sensor is available for this valve, see RE18300-30 for details. maximum operating pressure is 310 bar (4500 psi), maximum flow rate is 50 l/min (13.2 gpm), and port connections are G 3/8 SAE6 G 1/2 SAE8 and others. The voltage type is DC (AC only available via RAC connection) with a voltage tolerance of -10% to +10% for continuous operation and a coil lead temperature of 302°F (150°C) at ambient temperatures of ≤50°C (122°F). This valve is part of the 4WMM10 series and is designed for manual operation, where the position of the directional slide valve is changed by direct operation of the handle. When the slide valve is in the center position, such as the E model, ports P, A, B, and T are closed. When the handle is pushed forward, inlet port P is connected to port B and return port T is connected to port A. When the handle is pulled back, inlet port P is connected to port A and return port T is connected to port B, thus realizing on/off and directional control of the oil circuit.
