Proportional Directional Valve 4WRZ10W8-25-7X/6EG24N9EK4/D3M - Bosch Rexroth R900244328

The material pairing decides how long the seals last. The 4WRZ10W8-25-7X/6EG24N9EK4/D3M is matched with NBR to HL hydraulic fluid while controlling 25 l/min nominal flow.

Benefits

• NBR seals for HL hydraulic fluid, matched to mineral oil duty.
• 25 l/min nominal flow, up to 170 l/min flow at 315 bar.
• Internal pilot oil supply, external return, insensitive to counter pressure in the tank line.
• Spool symbol W8 with 3 switching positions across 4 ports.
• 8.22 kg, 24 VDC, external electronics, subplate mounting to ISO 4401-05-05-0-05.

Applications

It is intended for plants running ordinary hydraulic oil with controlled positioning axes. The fine nominal step suits short strokes and slow travel. Through the external amplifier card, characteristic and ramps can be matched to the axis.
