Directional control valves
VTHL offers a multiplicity of special equipment besides standard directional control valves. For example the NG 4 program exhibits extremely short switching times for dynamic requirements within the millisecond range.

Due to the compact building design with standing magnet (double solenoid coil with 4/3 valves) the valves can be integrated even in the smallest fitting spaces.

Directional control valves belong to the characteristics of the VTHL delivery program. These fast pilot valves make switching times possible, over 50% below the switching times of direct-controlled valves. Switching time adjustment, stroke limiter and monitoring are available as options.
