Proportional Directional Valve 4WRTE10W8-50L-4X/6EG24K31/F1M - Bosch Rexroth R901164220

Many axes need neither 25 nor 100 l/min but a rating in between. The 4WRTE10W8-50L-4X/6EG24K31/F1M works with a 50 l/min nominal flow in size 10 and is fed from its own pilot oil circuit.

Advantages

• Nominal flow of 50 l/min, rated between fine feed and fast stroke.
• External pilot oil supply and external return keep pilot pressure constant.
• Current command 4...20 mA on the on-board electronics.
• Operating pressure up to 350 bar, flow up to 170 l/min.
• Spool symbol W8 with three switching positions, four ports, ISO 4401-05-05-0-05.
• Weight of 8.46 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Applications

The nominal flow matches medium sized cylinders on forming and clamping equipment. The separate pilot circuit also allows clean operation in systems with an accumulator. Besides P, T, A and B, the manifold has to provide the X and Y ports.
