A differential cylinder pushes and pulls across unequal areas. Spool symbol V1 in the 4WRLE16V1-250L-4X/VPY/24A1 is cut for exactly that case, moving 250 l/min nominal flow at 350 bar operating pressure under a ±10 V command value.

Total price
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.
