General Description
Proportional directional control valves Model 4 WRA B 6 and 4 WRAE B 6 are direct operated spool valves. They control the direction and quantity of flow to an actuator, for smooth acceleration to a desired velocity. The valve is normally operated by integrated electronics or the appropriate amplifier card. The 4 WRA B 6 can be operated as a switching valve if proportional control is not required. Covered manual overrides are standard to simplify troubleshooting.

General Description
Proportional directional control valve Model 4 WRE is a direct operated spool valves. It controls the direction and quantity of flow to an actuator, for smooth acceleration to a desired velocity. The valve is normally operated by the appropriate amplifier card. The LVDT feedback device is mechanically linked to the spool. Spool position is fed back to the amplifier card for stroke position verification.
