valves
q
Hand-lever operated

q
Installation dimensions acording to
DIN 24 340 / ISO 4401 / CETOP RP121-H
The hand operated directional control valves are used
mainly to control start, stop and direction of fluid.
The valves consist of housing (1) with control spool (2)
and the actuating section (3). The actuating section
consists either of the hand lever (4) and of one or two
return springs (5), or of the hand lever (4) and the detent
assembly (6). The detent assembly holds the spool in its
last shifted position.
The directional control valves are being manufactured
as two-position and three-position valves (see table with
functional symbols).
The valve housing (1) is phosphate coated, the
components of the actuating section (3) are zinc coated.
