Describtion Pressure limiting valves are used to limit a system pressure in the hydraulics. They were specially developed for water hydraulics. Using these pressurelimiting valves post-connected valves or cylinders can be supplied with a continuously controllable reduced pressure in accordance with the circuit diagram. Pressure limiting valves are sealed by pressing two metal cones against one another. The max. working pressure should not exceed 650 bar.
The pressure limiting valve responds without delay when the preset system pressure is exceeded. It can be supplied for various different pressure levels.Within each pressure level it can be set continuously and finely on the spring column. A possible lead seal protects against unauthorized adjustment. All wear parts are made of corrosion resistant materials, easy to access and fast to replace. The mounting position can be freely chosen.
