Proportional Directional Valve 4WRZE10W9-50-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901032843

A separate pilot oil return keeps the pilot circuit clear of back pressure in the tank line. That is how this 4WRZE10W9-50-7X is built: internal pilot supply, external return, 50 l/min nominal flow and a plus or minus 10 V command.

Benefits

• A plus or minus 10 V command matches common analogue outputs, so no conversion to a current signal is needed.
• External pilot oil return separates the pilot stage from tank pressure in the working line.
• 50 l/min nominal flow at operating pressures to 315 bar, size 10 to ISO 4401-05-05-0-05.
• Concealed auxiliary actuation for emergency moves, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Weight 8.48 kg, NBR seals, hydraulic fluid class HL.

Applications

Typical places are test rigs, forming presses and power units with a shared return header. Because the pilot return is routed separately, response of the pilot stage stays the same even when tank pressure varies. The valve switches between three positions and serves four ports.
