Hydraulic Operated Directional
Control Valves
The directional control valves are of modular design and
comprise a housing (1) with a cylidrical spool (2) and
one or two operating elements (3) consisting of
hydraulic pistons (4) and return spring (5).
Three-position directional valves are fitted with two
hydraulic operating elements and two centering
springs. Two-position directional valves have only one
hydraulic operating element and one springs.
The basic surface treatment of the valve housing is
phosphate.
