Test benches run with a pilot pressure held constant so that the step response stays the same across the whole load range. This 4WRZE25 with spool symbol E is therefore piloted and drained externally, at 325 l/min nominal flow and 350 bar. The command value is ±10 V.

Description

A reproducible step response requires a pilot pressure that does not move with the load. That is why this version is piloted externally and drained externally, while delivering 325 l/min nominal flow at 350 bar operating pressure.

Benefits

External pilot supply holds pilot pressure constant across the whole load range.
External drain keeps the pilot chamber free of back pressure from the working line.
325 l/min nominal flow, maximum flow 870 l/min.
±10 V command with on-board electronics, 24 VDC supply.
20.28 kg on the standard size 25 interface ISO 4401-08-08-0-05.

Applications

Typical applications are material testing machines, servo hydraulic pulsers and development test benches with changing load. In production plants with strongly varying system pressure the behaviour stays equally uniform. NBR seals match HL hydraulic fluid.
