Product Application
Hydraulic sectional directional control 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 monoblock directional control valve,sectional directional valve's biggest advantage is this kind of valve are suitable for users to assemble on their own，which also can reduce stocks.
