HYDAC LCX-6 load-sensing sectional control valve

Click2Contact

The LCX-6 valve series is based on the existing LX-6 valve series and is designed for closed-centre hydraulic systems with variable displacement pumps while providing a compact design with space and weight reduction.

The LCX-6 valve series’ nominal pressure is 350 bar, and maximum flow rate at the pump port is 250 L/min (or 180 L/min with a pressure peak protection unit) and at working ports is 180 L/min with compensator and load holding function.

Features of the LCX-6 valve series include flow-optimised valve design; high mechanical and electrical resolution; compact size and low weight; modular design for up to 10 working sections; manual, hydraulic, electrohydraulic (on/off, proportional) types of operation (with or without hand lever); application-specific main spools with adjustable stroke limiter; and shock/anti-cavitation valves for protection of actuators.

Other features include adjustable load sense pressure limitation (mechanically or electro proportionally) that cause the compensator to block flow to the working A or B; and optional flange blocks for LS remote control of single sections.

The individual single sections of the LX-6 valve series are used 1:1 in the LCX-6 valve series and are therefore interchangeable; however, the inlet and end modules cannot be combined or exchanged between two valve series.

If only one hydraulic function is needed, the LCX-601 is the right choice. It consists of one mono section that does not require separate inlet and end plates as everything is included. It can be customised to different applications and machines.
