Direct Operated Directional Control Valve
Series D1VACharacteristics
Pneumatically controlled directional control valves of
series D1VA are based on the standard D1VW design.
The main spool is operated via an auxiliary spool of lager
diameter. Thus enables low operating pressures from 3
to 5 bar.
Pneumatic connection via thread G1/8 in the end caps.
