Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9ETK31/A1V - Bosch Rexroth R978916358

Anyone who has to move a lifting axis by hand in an emergency needs mechanical access at the valve. The 4WRZE10W8-85-7X/6EG24N9ETK31/A1V provides a concealed manual override and in normal service meters 85 l/min rated flow at 315 bar maximum.

Benefits

• Concealed manual override for the case that electrical actuation fails.
• 85 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
• Spool symbol W8, three switching positions, ISO 4401-05-05-0-05 pattern in size 10.
• Internal pilot oil supply and internal pilot oil return, build without a pressure reducing valve.
• Command value 10 V bipolar, 24 VDC supply, 8.48 kg, FKM seals for HL fluid.

Application

Stage lifts, under-stage machinery and heavy adjusting axes in event technology and plant engineering use this valve. The build without a pressure reducing valve assumes that pilot conditions are already limited in the circuit. Smaller rated flows in the same series are 25 and 50 l/min.
