Hydraulic valve

Hydraulic valve
The basic construction of the hydraulic valve manifold including spool, and driving the spool valve within the valve body for relative movement manipulation apparatus. The main form has a spool valve, poppet valve and ball; the body in addition to a body orifice or valve seat and valve fitting hole, there are external tubing into and out of the oil port and drain; actuated valves core in the valve body for relative movement means may be a manually adjustable mechanism, may be a spring or a solenoid, some occasions also driven by liquid pressure. On principle, the use of hydraulic valve spool relative movement in the valve body to control the on-off valve port and the size of the opening, in order to achieve pressure, flow and direction control. www.168fm.cn working hydraulic valve, the valve orifice size of all valves, valve inlet pressure difference between the oil port and through the relationship between flow valve orifice flow equation are consistent with (q = KA · Δp m) , but a variety of valve control parameters vary only.
