Proportional Directional Valve 4WRDE27V500L-6X/MXY/24A1 - Bosch Rexroth R901527733

A separately filtered pilot circuit extends the service life of the pilot stage considerably. The 4WRDE27V500L-6X/MXY/24A1 is laid out for that, routing pilot supply plus pilot drain to the outside, controlling 500 l/min nominal flow, passing 1000 l/min at peak.

Key benefits

• External pilot oil supply plus external return let the pilot circuit be filtered on its own.
• Nominal flow of 500 l/min alongside 1000 l/min peak flow in size 27.
• Operating pressure of 270 bar with internal piston position feedback plus on-board electronics.
• Command value of plus or minus 10 V on a 7-pole connector to EN 175201-804.
• Interface ISO 4401-08-08-0-05, mass of 19.5 kg, NBR seals, HL hydraulic fluid.

Technical data

Applications

This build sits in rolling mills, forging plants plus large injection moulding machines where oil takes heavy load. A dedicated pilot circuit permits finer filtration than the main circuit. Provide generous return cross sections at 1000 l/min peak flow.

Manufacturer
