Proportional Directional Valve 4WRLE16V1-250L-4X/VPY/24A1 - Bosch Rexroth R901537972

In a differential cylinder the piston area and the annulus area differ, and a symmetrical valve then produces unequal speeds. The 4WRLE16V1-250L-4X/VPY/24A1 compensates with spool symbol V1, at 250 l/min nominal flow and 350 bar operating pressure.

Benefits

• Spool symbol V1 is matched to the area ratio of differential cylinders, across three switching positions and four ports.
• 250 l/min nominal flow and up to 800 l/min maximum flow at 350 bar operating pressure.
• ±10 V command value at the on-board electronics, 24 VDC supply.
• FKM seals for HL hydraulic fluid, CE conformity.
• Valve mass 11.84 kg on the ISO 4401-07-07-0-05 mounting pattern.

Application

Intended for feed and press axes built around differential cylinders, for example in sheet metal work and fixture building. A voltage command suits installations where control card and valve sit close together. The standard mounting pattern makes replacement of an existing size 16 valve simple.
