Proportional Directional Valve 4WRLF16V250L-4X/MPT00/24TD95 - Bosch Rexroth R901547329

A proportional valve is only as accurate as the feedback from its spool. The 4WRLF16V250L-4X/MPT00/24TD95 measures spool position internally and uses it to control 250 l/min nominal flow, up to 800 l/min at peak, at 280 bar operating pressure. Fieldbus electronics are integrated in the valve, so command value and enable acknowledgment sit right at the connector.

Benefits

• 250 l/min nominal flow in size 16, up to 800 l/min maximum at 280 bar.
• Integrated fieldbus electronics, the valve needs no separate amplifier card and takes voltage supply and enable acknowledgment through one plug.
• Internal spool position feedback with a linear characteristic curve and spool symbol V.
• Three switching positions across four ports, pilot-operated with internal pilot oil supply and internal pilot oil return.
• Connection diagram ISO 4401-07-07-0-05 for subplate mounting at a weight of 12.41 kg.
• UKCA conformity for electromagnetic compatibility under SI2016/1091, with NBR seals for hydraulic fluid HL.

Applications

The valve earns its place wherever a large cylinder or motor has to accelerate and stop cleanly, for example in presses, rolling mills and test rigs. UKCA conformity helps on machines shipped to the United Kingdom. Fieldbus control ties the valve into the machine controller without spending one analog output per axis.
