These double cross anti-shock valves are used to limit the pressure on both hydraulic motors’lines at a certain setting pressure. They are principally used both as anti-shock valves and to set the two pressure lines with different adjustment values. This flanged version grant a compact assembly with few pressure drops. The external body is made of high resistance steel and externally protected from oxidations by zinc treatment. On request we can supply a zinc/nickel treatment to increase the oxidation resistance when the valve has poor protection or it is located in external environments.
