Description

The world of hydraulics would be inconceivable without pressure control valves. They limit or control the pressure in hydraulic systems or switch volume flows as a function of signal pressures. We offer four types of pressure valves in our delivery program:

1. Pressure-relief valves
These valves are switching valves. They open at a specified, adjustable pressure.

2. Pressure-reducing valves
These valves are control valves. They keep the output pressure constant regardless of the input pressure. The output pressure is adjustable and lower than the input pressure.

3. Check valves
These valves are switching valves. They allow flow in one direction and block it in the opposite direction.

4. Accumulator charging valves
These valves are primarily intended for regulating the charging process of hydraulic accumulators in hydraulic systems with fixed displacement pumps. After reaching a specified (switch-off) pressure, the valve opens and switches the pump to unpressurized circulation. The switch-off pressure can be adjusted within a specific pressure range. If the system pressure drops below a specified switch-on pressure, the pump charges the hydraulic accumulator again until the switch-off pressure is reached. Selectable fixed switching hysteresis curves provide optimum system matching.
