Pressure-control valve with safety function - Hawe Hydraulics

The type CLK pressure-control valve has an added safety function that provides operational ease in hydraulic systems where temperature increases and/or external load peaks can cause problems.When closed, the seated valve is leak-free, eliminating the need for additional check valves or continuous refeeding. The valve offers 5.8-gpm flow at 380 bar (5,500 psi) for systems with a maximum pressure of 500 bar (7,250 psi). Built as a screw-in cartridge valve, other versions are available for mounting within valve banks, reducing the pressure for subsequent valves or as part of the NG6 intermediate plate for individual pressure control.
