Directional control valve is used to control actuators direction start and stop.

Example of directional control valve. Mounting configuration according to CETOP R35H ISO 4401 and DIN 24340 Wide variety of spool types including detent and interchangeable spools and bodies. A b Figure 1. Basics of Directional-Control Valves.

One example is a 43 or 4-ports 3-position valve. Directional control valves DCVs are used to stop and control the direction of flow in a fluid power branch circuit. 27 Directional Control Valves.

As the surface of the spool on that side is larger approximately double than on the spring side right the spool is moving. Compact five annuli body design. Directional control valve will be operated by receiving the signal and signal might be manual hydraulic pilot signal electric signal or electronics signal.

So that hydraulic valve can start stop or change the movement. The directional control valves can be used to start stop and to change the fluid flow in a hydraulic system. Pumps and Flow Control.

Find below a hydraulic circuit that describes how a directional control valve works. Tolerances are very tight in order to handle the high pressure and avoid leaking spools typically have a clearance with the housing of less than a thousandth of an inch 25 µm. Directional valves are used to direct fluid air or oil to reverse the flow direction and extendretract the cylinder.

45 Flow Control Valves. P T A and B. A water faucet allows flow or stops flow by manual control.
