Valve is a large type of agricultural machinery accessories, and many kinds of applications are very extensive, which is very common in agricultural machinery control system. It is mainly the control part of the fluid conveying system. It has the functions of cut-off, regulation, diversion, countercurrent prevention, stabilization, diversion or overflow relief.

Valves are usually composed of body, bonnet, seat, opening and closing parts, driving mechanism, seals and fasteners. The control function of the valve is realized by driving mechanism or fluid to drive the lifting, sliding, swing or rotary motion of the hoist to change the size of the runner area.
