Sizing a valve to the actual demand saves throttling losses. This 4WRTE25E220L-4X works at 220 l/min nominal flow instead of 350, holds 350 bar operating pressure and takes its command value as a ±10 V voltage.

Description

An oversized valve permanently works in the lower part of its characteristic curve, where command value resolution is at its worst. At 220 l/min nominal flow this 4WRTE25E220L-4X sits closer to the operating point of many axes without giving up the 870 l/min maximum flow.

Benefits

220 l/min nominal flow, matched to the real operating point of medium axes
870 l/min maximum flow retained as reserve
Spool symbol E, three switching positions, internal spool position feedback
Internal pilot oil supply, external pilot oil return
Analog ±10 V command value, ISO 4401-08-08-0-05 interface, 350 bar

Applications

Sensible in plants that mostly run at part load and where oil temperature and cooling capacity are an issue. Less throttling across the control edges means less waste heat in the tank. An analog voltage output of the control system is enough to drive it.

Manufacturer

Bosch Rexroth, material number R900977350, type 4WRTE25E220L-4X/6EG24EK31/A1M, component series 4X.
