Pressure drop ∆p [bar (PSI)]
Flow Q [l/min (GPM)]
› Directional control valve, internally or externally pilot operated with mounting interface
acc. to ISO 4401, DIN 24340 (CETOP 08)
› Driven by an ISO 4401-03 (CETOP 03) solenoid operated directional valve (RNEH)
or a hydraulic pilot operated directional valve (RNH)
› Electrohydraulic and hydraulic control ports X and Y
› Version for high pressures 420 bar (6090 PSI) available
› High transmitted hydraulic power, optimized design to minimize the pressure drop
› Flexibly changed from internal pilot or drain to external by inserting or removing
threaded plugs in the main control valve body
› Wide range of interchangeable spools and valve controls available
› Soft-shift, spool speed, main stroke limiter control options
› In the standard version, the valve housing is phosphated for basic surface corrosion protection
and as preparation for painting. Steel parts are zinc-coated for 240 h salt spray protection acc.
to ISO 9227. Enhanced surface protection for mobile sector available for the valve housing
and steel parts (ISO 9227, 520 h salt spray).
