When pressure at port P drops below pilot level, an external pilot oil supply keeps the valve alive. This 4WRTE25V220P is built that way, at 220 l/min nominal flow, 350 bar operating pressure and an analog ±10 V command.

Description

Plants that unload pressure or run on accumulators put pilot-operated valves in trouble as soon as pilot pressure disappears. The 4WRTE25V220P-4X/6EG24TK31/A1M avoids that through external pilot oil supply with internal pilot oil return, while metering 220 l/min at 350 bar.

Benefits

External pilot oil supply keeps pilot control fed even when working pressure at P is unloaded.
Internal pilot oil return saves an extra line back to tank.
220 l/min nominal flow, 870 l/min maximum, from a valve of 18 kg.
Analog ±10 V command straight from the controller, with internal spool position feedback.
Spool symbol V offers a fine metering range around centre.

Applications

Sensible in accumulator circuits, power units with variable displacement pumps and anywhere system pressure swings widely during the cycle. Control quality is retained at low working pressure too. Mounting pattern ISO 4401-08-08-0-05, HL hydraulic fluid.
