Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9EK31/F1M - Bosch Rexroth R901505547

If the plant already limits the pilot pressure, a separate pressure reducing valve inside the directional valve is redundant. The 4WRZE10W8-50-7X/6EG24N9EK31/F1M is therefore supplied without it, regulates 50 l/min nominal flow from a 4...20 mA current command and can be shifted by hand through a concealed auxiliary actuation.

Benefits

• Version without pressure reducing valve for plants whose pilot pressure is already limited.
• Concealed auxiliary actuation allows the pilot valve to be shifted without electrical power.
• Spool symbol W8 with 50 l/min nominal flow, maximum flow 170 l/min.
• Internal pilot oil supply and external pilot oil return, operating pressure up to 315 bar.
• Command value 4...20 mA, 24 VDC supply, weight 8 kg.

Technical data

Applications

Plants with a centrally regulated pilot pressure, such as large press lines and test fields, save the duplicated pressure reducing valve. The concealed auxiliary actuation helps during commissioning and fault finding without being operated by accident in service. The subplate mounting follows ISO 4401-05-05-0-05 in size 10.
