4/3 servo solenoid valves with on-board electronics (OBE), positive overlap and position feedbac
4WRPE 4WREF 4WREE 4WREQ 4WREEM Series Hydraulic Proportional Directional Control Valve 4WREE 10 W1-75-2X/G24K31/A1V
Directional valves type WE are solenoid operated directional spool valves. They control the start, stop, and direction of a flow. These directional valves basically consist of housing; one or two solenoids; control spool; and no, one, or two return springs. A full array of spools are possible with variations in voltage and electrical connection, all within the program. Flow and pressure rates from 4000 PSI to 5000 PSI and 21 GPM to 32 GPM cover a wide range of applications.
Features
– Directly operated NG6 and 10 valves with positive overlap, actuated on both sides and position-controlled, symbol E or W – Control solenoid with on-board electronics (OBE), deadband compensation and gain calibrated at the factory
– Electrical connection 6P+PE (standard), signal input: differential amplifier with interface A1 = ±10 V (F1 on request)
– For subplate attachment, mounting hole configuration NG6 to ISO 4401-03-02-0-94 and NG10 to ISO 4401-05-04-0-94
