Description

This variant combines a 4...20 mA current command value with fully internal pilot oil routing, which means the simplest piping at the manifold. Nominal flow is 220 l/min at operating pressures up to 350 bar.

Advantages

Command value 4...20 mA, insensitive to cable length and electrical noise
Internal pilot oil supply and internal return, only four main ports to pipe up
Nominal flow 220 l/min, maximum flow up to 870 l/min
Symbol W6 relieves the actuator in mid position
Linear characteristic curve with fine control range, operating pressure up to 350 bar
Connection diagram ISO 4401-08-08-0-05, 17.84 kg, NBR seals for HL hydraulic fluid

Applications

Typical for feed axes on presses and test rigs with an unpressurised return. Because command value and supply share the same 7-pole connector, wiring stays simple. An ISO 4401-08 subplate is enough for a replacement.
