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.

For cylinder applications prone to vibration with flow rates from 5 to 60 l/min and maximum pressures up to 450 bar. Multi-section masts moved by cylinders often tend to vibrate. If damping is insufficient, this can also be caused by the actuation of a cylinder. The often necessary reduction of the consumer speed and the clamping of the cylinders can be avoided by choosing WESSEL valves. Hardened steel for the housing and spool ensures high wear resistance and safety! The valves can be connected using a hollow bolt or with 4 screws. Variants are available for one (single valve) or both cylinder sides (double valve).

MCV-1SP is a proportional directional control valve system in sectional design for mobile applications. The valve consists of three main components: – inlet plate – directional control valve sections – end plate. Control is proportional, either electrical or hydraulic; manual operation via a hand lever is also possible. The MCV-1SP directional control valve can be used as a main control valve or as an additional section for functional expansion in mobile machinery. By connecting to the existing hydraulic system, additional work functions can be easily integrated into the machine. Electrical or hydraulic pilot control options can be selected.

The PRV-DSU pressure relief valve is a direct-acting, robust valve for small flow rates up to 10 l/min. The valve can withstand up to 500 bar and is delivered pre-set. This valve is suitable, for example, for lifting cylinders in mobile cranes. The pressure increase, which can be caused by heat when cylinders are not moving, is prevented with this valve.
