Proportional Directional Valve 4WRZE10W6-85-7X/6EG24TK31/A1D3M - Bosch Rexroth R900716434

Some manifolds supply filtered pilot oil yet drain the return internally. The 4WRZE10W6-85-7X/6EG24TK31/A1D3M is built for exactly that case, taking pilot oil from outside, releasing it into the tank gallery inside the valve, and regulating 85 l/min nominal flow up to 315 bar operating pressure.

Benefits

• External pilot oil supply with internal pilot oil return, matching manifolds that run their own pilot pump.
• Nominal flow 85 l/min through spool symbol W6, maximum flow 170 l/min.
• Operating pressure up to 315 bar, four ports to ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot circuit limits the pilot pressure.
• On-board electronics, ±10 V command value, 24 VDC, weight 8.44 kg.

Applications

This combination of pilot paths appears on press lines and steelworks plants whose pilot circuit is fed centrally but drained locally. The valve sits in the usual size 10 port pattern. Command value and power share the 7-pole connector to EN 175201-804.

Manufacturer

Bosch Rexroth lists the valve under R900716434. Type code 4WRZE10W6-85-7X/6EG24TK31/A1D3M is decoded in datasheet RE 29115, which also holds characteristic curves and the port pattern, RE 07600-B adds the fluid data.
