VS30 valves are used in hydraulic systems as a component to establish the supply sequence of several actuators connected to a single power source. In a system with two actuators, the valve is installed between the power source (1) and the actuator (2) that is to be supplied second. The opening pressure value is set using a screw (adjustment with an Allen key, locked with a locking nut). The valves are equipped with mounting holes. Special attention should be paid not to set the pressure value higher than 260 bar (maximum operating pressure for the aluminum body). Material: aluminum (body), galvanized steel (valve). Sealing: NBR. Operating temperature: from -20°C to +100°C.
