Proportional Directional Valve 4WRZ10W8-85-7X/6EG24N9TK4/M - Bosch Rexroth R900741669

Not every manifold has a spare bore for the pilot drain. The 4WRZ10W8-85-7X/6EG24N9TK4/M is supplied with pilot oil externally and drains it internally, at 85 l/min nominal flow and up to 170 l/min in the main channel.

Benefits

• External pilot supply, internal pilot drain, a separate drain line is not required.
• 85 l/min nominal flow with spool symbol W8 and 3 switching positions.
• 315 bar operating pressure on the ISO 4401-05-05-0-05 pattern, subplate mounting in size 10.
• 7.74 kg including a concealed manual override for emergency operation.
• 24 VDC with external electronics through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

This pilot oil variant suits manifolds whose pilot pressure comes from a separate circuit while the drain stays combined with the tank channel of the valve. That cuts the number of bores in the block without making the pilot circuit depend on working pressure. The valve serves feed axes and press axes with an analogue command signal.
