Proportional Directional Valve 4WRLE16V250L-4X/VXY/24A1 - Bosch Rexroth R901555419

Some axes need resolution in slow motion and a sudden flood of oil in rapid traverse. The 4WRLE16V250L-4X/VXY/24A1 covers both, with 250 l/min nominal flow for closed-loop work and up to 800 l/min when the cylinder has to run through, in each case at 350 bar operating pressure.

Benefits

• 250 l/min nominal flow with up to 800 l/min maximum flow from a single size 16 body.
• Spool symbol V is shaped for a fine metering range around centre, across three switching positions and four ports.
• ±10 V command input on the on-board electronics, 24 VDC supply.
• FKM seals are rated for higher oil temperatures than NBR and suit HL hydraulic fluid.
• CE conformity, 11.6 kg valve mass, ISO 4401-07-07-0-05 mounting pattern.

Application

A match for presses and clamping axes that alternate between slow control and fast travel. The ±10 V command can be fed straight from an analogue card. At 11.6 kg the valve belongs on a subplate rated for that mass in size 16.

Manufacturer

Bosch Rexroth lists this valve under material number R901555419. Seals are FKM, and electrical connection uses a 7-pole connector (6 + PE) to EN 175201-804.
