Hydraulic Control Directional Valve

The YZH170CF-30 is a compact, monoblock type valve that can contain 1 to 4 working sections. Parallel or series connection between the working sections can be realized internally, and they are all equipped with their own load holding check valves and can be supplied with single or multiple pumps. The valves are currently controlled hydraulically. The valves are designed for system pressures up to 250 bar, with secondary pressure relief valves in the working ports on request, up to a maximum pressure setting of 280 bar, and a flow range of 0-170 L/min. The return flow rate can be as high as 330/min (depending on the type of spool) in each of the working ports. The valve can be used in many different types of equipment, from backhoe loaders, garbage trucks, container trucks, forklifts to surface and underground coal miners, and it is also advantageously used in industrial applications.
