ZDa-L15 series 60l/min,hydraulic manual control valve for kids hydraulic excavator,manufacturer in china
Hydraulic monoblock valve is controlling component of the hydraulic system,which is used for adjusting the direction,pressure and flow.The valve is widely used in the hydraulic system of forklift,sanitation vehicle and light loading machines.Comparing the sectional control valve,monoblock valve's biggest advantage is excellent sealing
performance.Also it has a smaller volume，which is suitable for the appilication scene where requires high flow.
