ZT-L20 series(80l/min),control valve hydraulic 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.

Main Features
