Hydraulic control valves are employed in the moving of hydraulic fluid when required in hydraulic equipment. They work like simple control valves. The primary task of these valves is to regulate the flow and pressure of the liquid to enable the equipment to work properly. They come in a wide variety, ranging from simple ones that only switch on and off to more complex ones that control flow to high accuracy.

The parts of a hydraulic control valves are many. The basic components include a main casing, seat, bonnet and disc. Some valves have these components in multiples, while some have them in singles. The outermost shell of the valve is its main casing. The seat is the place where the connection of the valve is made. The bonnet is the part of the main casing that can be opened for any repairs to be made to the valve. The disc is a seal, which prevents leakage from the point where it is connected to the hose.

The inside of the valve can also vary with the design of the valve. It can vary from a simple tapering cylinder, which regulates the quantity and pressure of fluid to valves of the port type that can only be turned on or off. A few valves have a split that is used to divide the direction of fluid into two or to alternate it. Such valves are known as directional valves. A number of hydraulic control valves also have a device known as the backflow preventer that prevents the fluid from flowing in the opposite direction.

Unlike pressure reducing valves, hydraulic control valves can be switched on or off manually or by machines. In some of them, a hydraulic control performs this task.  In float valves, the float controls the switch.
