Proportional Directional Valve 4WRDE25V1-350L-6X/MXYWG/24A5 - Bosch Rexroth R901520296

When a press or a test rig has to hold speed and position at the same time, a switching valve is not enough. The 4WRDE25V1-350L-6X/MXYWG/24A5 controls its spool through internal position feedback while passing 350 l/min nominal flow at up to 350 bar.

Benefits

• 350 l/min nominal flow in size 25, rated to a maximum flow of 870 l/min.
• Internal spool position feedback holds the command value under changing load, symbol V1 with 3 switching positions.
• Analog ±10 V command value into the on-board electronics, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• External pilot oil supply with external pilot oil return keeps the pilot circuit separate from the main circuit.
• ISO 4401-08-08-0-05 connection diagram for subplate mounting, 18.8 kg, NBR seals for HL hydraulic fluid.

Technical data

Application

Hydraulic presses, injection moulding machines and materials testing rigs with large cylinder volumes are the usual home for this size. The 350 l/min stage covers fast traverse, while spool feedback keeps the slow approach accurate. The 4 ports connect the valve as a standard four-way function.

Manufacturer

Bosch Rexroth, material number R901520296, product family 4WRDE. The amplifier electronics sit inside the valve, so a separate controller card in the cabinet is unnecessary.
