Proportional Directional Valve 4WRZ10W8-25-7X/6EG24ETK4/M - Bosch Rexroth R900977757

A valve with internal pilot routing needs only the four main ports in the manifold. The 4WRZ10W8-25-7X/6EG24ETK4/M does exactly that and adds the fine grading of 25 l/min nominal flow.

Benefits

• 25 l/min nominal flow for slow motion that resolves well.
• Internal pilot supply and internal pilot drain, no extra pilot lines in the manifold.
• Spool symbol W8, 3 switching positions on the ISO 4401-05-05-0-05 pattern.
• 315 bar operating pressure at 8.24 kg, NBR seals for HL hydraulic fluid.
• 24 VDC with external electronics, 7-pole (6 + PE) plug to EN 175201-804.

Applications

This combination suits compact power units with small cylinders, for example on clamping, adjusting and infeed axes. Pilot pressure is taken from port P, so a sufficient minimum pressure has to be present there. Because no separate pilot lines are required, the manifold stays lean and assembly time short.
