What is the directional control valve?

The directional control valve is a device capable of controlling air flow or liquids. A very simple example is the control valve, a design that allows the material to move in one direction without permission of the return flow. Direction control valves are used on a wide range of systems and devices and are particularly important for hydraulics. Their suggestions can be quite complex.

There are two important properties of the direction control valve. One of them is the number of ports. One valve can receive input from a number of sources, not only one; For example, four port valve has four inputs. The second is the number of positions in which the valve can be placed and determines how many different ways they can direct the materials it controls. The more ports and positions, the more functionality available to the valve when it is open or closed. Pneumatic direction control valves operate with air. The design in both cases is similar, with the valve having a seal to be contained and control. By means of a directional riverThe tiding valve can be created a pressure system, directing the materials through the device without physically manipulating, and performing a wide range of other tasks.

control systems for these devices are very variable. Some may be controlled manually, allowing people open and close ports and change the position. Others are remotely operated using mechanical settings or computer control systems. The direction control valve can be controlled from the distance in the settings where it could be dangerous to be in the same room as the device, and the remote control systems can also be designed for automation, allowing the system to handle the valves as needed. In an emergency, the system can open quickly or cztratit valves to solve the safety situation.

direction control valve can be a weak point in the system as it contains moving parts and they can be worn with timem, eventually create leaks or freeze up. The valves must be checked and maintained regularly and may require periodic oiling or lubrication, along with the replacement of components such as seals, how worn. The failure of the valve can cause disaster and the goal of regular inspections is to identify problem valves and service or replace before they become a problem.
