Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9K31/F1M - Bosch Rexroth R901067677

At 520 l/min a small deviation in the command already moves a noticeable amount of oil. This size 32 build therefore takes its command as a 4 to 20 mA current signal and runs on a standalone pilot circuit, at up to 350 bar operating pressure.

Key benefits

• 520 l/min nominal flow, with up to 1600 l/min through the size 32 body
• Current command value 4 to 20 mA into the on-board electronics, 24 V DC supply
• External pilot oil supply and external return, no pressure reducing valve built into the unit
• 350 bar operating pressure, 4 ports, 3 switching positions, spool symbol W8
• NBR seals, hydraulic fluid HL, 43.42 kg, UKCA declaration to SI2016/1091

Applications

A match for hoisting gear, forging presses and continuous casting plants with large cylinders. The external pilot circuit allows reliable shifting even at low working pressure. The pilot return has to be routed separately to tank.
