  • Inquiry

YDL-L20 series pilot hydraulic directional control valves are developed on DL-L20 manual control valves. It changed the control way from manual to pilot hydraulic which improves  the heavy manual control situation. Especially, it can be controlled by remote control with the pilot hydraulic control way. The power beyond function is on the YDL-L15 series, it is able to be connected with other hydraulic valves in series. The features of YDL-L20 pilot hydraulic control valves are compact construction, high working pressure, better working performance, reliable working, remote controlling and etc. Besides that, it realizes to control many working functions by remote control. The valves are widely used on mechanical machines, sanitation machines, mining machines and other machines’ hydraulic systems.
