Proportional Directional Valve 4WRTE32W6-600P-4X/6EG24K31/A1M - Bosch Rexroth R987171978

Large flow and fine metering around centre position rule each other out on plain spool valves. The 4WRTE32W6-600P-4X/6EG24K31/A1M solves that with a linear characteristic plus fine control range while handling 600 l/min nominal flow at 350 bar.

Benefits

• 600 l/min nominal flow, flow capability up to 1600 l/min in size 32.
• Linear characteristic with fine control range for accurate metering close to neutral.
• Internal spool position feedback, giving low hysteresis and repeatable positions.
• External pilot oil supply and external return for systems with their own pilot circuit.
• ±10 V command value on on-board electronics, 24 V DC, 7-pole connector (6 + PE).
• 36.94 kg weight, symbol W6, ISO 4401-10-09-0-05 interface, NBR seals.

Application

The valve drives main axes on presses, stretching lines and test rigs that swallow a lot of oil in rapid traverse yet must stop accurately at the end of the stroke. External pilot routing allows operation even when working pressure is temporarily low. No separate amplifier is needed because the electronics sit in the valve.
