Product Description Applications:Mainly used in 20 ~ 25T mobile crane fixed pump system, and related similar circuit application in agricultural machinery, road and bridge machinery, sanitation machinery, mining machinery and etc. The multi-way valve is a load-sensitive multi-way valve, and the flow rate is independent of the load. The valve is a double section structure, which can be expanded according to the needs, max section is 7 working section; the valve is integrated with an oil return back pressure valve, which adopts a parallel circuit. That can effectively protect the radiator; the flow can be adjusted through the valve spool stroke, and each working section has a pressure compensation function; the working port can be set with a secondary pressure relief valve according to the needs; the control forms is hydraulic control.DimensionProduct ParametersModel4MHPCV280-28Rated pressure26MPaRated flow rate280L/minWorking oil temperature-20oC~+90oCWorking fluidmineral oil (HL,HLP) according to DIN51 524 standardFluid viscosity range10~380mm2/sThe max allowable pollution degree of oillevel 9 according to NAS1638Recommended filter filtration precisionminimum β10≥75* If you have lower temperature requirements, please contact YUZHOU engineer.
