Direct operated proportional spool valve with
integrated electronics in flange design NG4-Mini acc. to Wandfluh standard with 4 ports.
The valve possesses an integrated positional
control of the valve spool. This assures a minimal hysteresis and improved dynamic characteristics. Housing for electronics with protection class IP67 for harsh environment. The
spool valve is designed acc. to the 5 chamber
principle. The volume flow is adjusted by Wandfluh proportional solenoids (VDE standard 0580). Low pressure drop due to the body design and spool profiling. The spool is made of
hardened steel. The body made of high grade
hydraulic casting is painted. The solenoids are
zinc coated and the housing for the elctronics
is made of aluminium.
