Pressure Control Valves
Direct-controlled VTHL pressure control valves are constructed in seat or piston design and are characterized by small, reproducible switching limits. Almost all applications can be covered.

The pressure control valve cartridges can be built directly into control blocks, saving space.

VTHL accumulator charging valves with constant switching limit and soft switching are particularly suitable for drive systems with a distinctly cyclic oil requirement.

With use of memory load valves it is sufficient to design the installed drive power for the average need.

All pressure control valves can be equipped with a gauge connecting valve.
