Product Summary

The manual directional valves are one of the most fundamental parts in hydraulic machinery.   They allow fluid flow into different paths from one or more sources. They usually consist of a piston inside a cylinder which is manually controlled. The movement of the cylinder restricts or permits the flow, thus it controls the fluid flow. Directional control valves are mainly two types: Hydraulic and Pneumatic. Hydraulic directional control valves are for a liquid working fluid (e.g. water, hydraulic oil) and pneumatic directional control valves are for a gaseous (usually air) working fluid. They are generally specified using the number of ports and the number of switching positions. It can be represented in general form as np/ns, where np is the number of ports connected to the direction control valve and ns the number of switching positions.

In addition, the method of actuation and the return method can also be specified. Considering the valve in the given figure, it will be specified as 4-way, 3-position direction control valve or 4/3 DCV since there are four ports and three switching positions for the valve. Again, considering the figure given above, port 3 is called the pressure port which is connected to the pump. Port 4 is the tank port and is connected to the tank (or reservoir) . Ports 1 and 2 are called working ports and are connected to the actuator.

The two primary characteristics for selecting a manual directional valve are the number of fluid ports and the number of directional states, or positions, the valve can achieve. Valve ports provide a passageway for fluid (air or hydraulic fluid) to flow to or from other components. The number of positions refers to the number of distinct flow paths a valve can provide.
