Proportional Directional Valve 4WRZE16E150-7X/6EG24N9ETK31/A1V - Bosch Rexroth R900945995

Internal pilot oil supply and internal pilot oil return keep the manifold simple, because no additional control line has to be routed. The pilot-operated size 16 directional valve converts a ±10 V command value into 150 l/min nominal flow and withstands 350 bar operating pressure.

Benefits

• Nominal flow 150 l/min, maximum flow 460 l/min at 350 bar operating pressure.
• Internal pilot oil supply and return, subplate mounting to ISO 4401-07-07-0-05 is all that has to be prepared.
• On-board electronics with ±10 V command value, 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804.
• Spool symbol E with 3 switching positions and 4 ports, concealed auxiliary actuation for commissioning.
• Version without pressure reducing valve in the pilot circuit, suited to an already regulated pilot pressure.
• FKM seals for HL hydraulic fluid, weight 11.45 kg.

Applications

Typical duty is on presses, injection moulding machines and test rigs where a size 16 cylinder is accelerated and braked under a continuous command signal. The concealed auxiliary actuation lets the spool be moved by hand while the machine is de-energised. Where the pilot circuit already carries a suitable pressure, the version without a pressure reducing valve fits directly.
