Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9TK31/F1M - Bosch Rexroth R901018110

External supply with internal drain is the combination for plants that have a pilot pressure unit and a short path to tank. This size 32 valve is built that way and controls 520 l/min nominal flow at up to 350 bar.

Key benefits

• External pilot oil supply from the pilot pressure circuit, internal pilot oil return through the tank port
• Current command value 4 to 20 mA, resistant to electrical interference nearby
• 520 l/min nominal flow, with flow up to 1600 l/min in size 32
• Operating pressure up to 350 bar, 4 ports, 3 switching positions, spool symbol W8
• 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804, 43.6 kg

Applications

Suited to power units where pilot pressure is generated centrally and distributed. The internal drain shortens the pipework but calls for a tank port with low back pressure. Through the external pilot circuit the valve can also be tested while the working circuit is unpressurised.
