Technical data
Directional Control Valves
Series D1DL, D3DL, D4L, D9L
The D1DL, D3DL, D4L and D9L are 5 chamber 4/3 or
4/2 way directional control valves. They are operated by
a hand lever which is directly connected to the spool.
The hand lever can be located either on the A or B side.
Spring offset and detent designs are available.
