Proportional Directional Valve 4WRTE10V50P-4X/6EG24K31/A1M - Bosch Rexroth R900768178

A test rig with its own pilot pump does not need a valve that draws from the working circuit. The 4WRTE10V50P-4X/6EG24K31/A1M is supplied and drained externally, meters 50 l/min nominal flow with spool symbol V and holds spool position through internal feedback, at up to 350 bar.

Benefits

• Size 10 with spool symbol V, rated at 50 l/min nominal flow.
• Pilot oil comes from an external circuit and leaves through an external return, keeping pilot pressure separate from working pressure.
• Spool position control works with internal feedback, and the characteristic curve is linear with a pronounced fine control range. Operating pressure reaches 350 bar.
• Command value input ±10 V on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• NBR seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 8.43 kg weight.

Applications

Applications include force and position control on materials testing machines, clamping axes and smaller forming presses. The 50 l/min suit medium cylinders at moderate speeds. Because the pilot circuit is separate, control quality survives pressure dips in the main circuit.
