Lock Valves for Outrigger Cylinders

Application description

Check Valves Cartridge

Double check valves in cartridge design can be screwed directly into the outrigger cylinder. The valve provides protection against a load dropping in the event of a line break in the supply lines. The valves are designed as pilot-operated valves. Hardened components (seat and cone) guarantee zero leakage in the rest position and a long service life. The valve is suitable for up to max. 70 lpm and can withstand pressures up to 500 bar. A screw-in housing is available for the valve.

In a second design, the piston rod side is preloaded only by a pressure valve. This ensures safe holding in the retracted position and absolutely vibration-free extension at low inlet pressures.
