Logic Valves

Logic valves are a special type of hydraulic valves that work on the principle of controlling the flow depending on the pressure in the system. They do not have classical controls such as solenoids or levers, but are opened and closed based on the difference in pressure between different ports. These valves can perform various logic functions such as AND, OR or NOT in hydraulic systems.

Shut-off valves are used in hydraulic circuits with accumulators, among other things, and have the task of supplying the pump's volume flow to the accumulator until the pressure preset on the valve is reached, as soon as the preset pressure is reached, the valve switches the volume flow of the pump to the tank.
