Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900957686

A voltage interface at the controller and a loaded tank return in the plant do not rule each other out, but they call for the matching valve version. This 4WRZE32W8-360-7X combines a plus or minus 10 V command with an external pilot oil return and delivers 360 l/min nominal flow.

Key benefits

• Analog command value of plus or minus 10 V, directly compatible with PLC or axis controller analog outputs.
• Internal pilot oil supply without an extra pump, external return free from the influence of back pressure.
• 360 l/min nominal flow at a permitted 1600 l/min and 350 bar operating pressure.
• Three switching positions, four ports, connection diagram ISO 4401-10-09-0-05.
• Concealed auxiliary actuation and a 7-pole connector (6 + PE) to EN 175201-804 for service and wiring.

Technical data

Applications

Typical systems are presses and lifting axes with a cooler or filter in the return line whose control works with an analog voltage. Because the pilot return runs its own way, switching time stays reproducible even at high return pressure. HL oil is the intended fluid, and the FKM seals tolerate higher temperatures with it.
