General Description
3-Way Rotary Spool Valve. The DM103 Series Valves
are suited for any 3-way application (such as a selec-
tor function) where manual operation is desired.
For additional information see Technical Tips
pages MV1-MV2.
Features
•
Several lever and knob options available
•

Operation
The K, LD, and FKD options require a full 90° rotation
to shift the spool from one offset position to the other.
The LN and FKN options require a full 45° rotation
from center to either offset position. The knob (or lever)
position indicator can be positioned anywhere within
the 360° circle.
