A valve is a unique device that blocks a tube or a pipe either entirely or partially to change or check the amount of fluid that passes through it. Different types of Flow Control Valves typically respond to signals generated by individual devices and temperature. Their kinds are different
kinds of valves that are used by different types of industries in major world countries.
Gate Valves
These are kinds of shutoff valves that operate both in the open and closed positions. It consists of seats and stems as the main components .seat and the stem is responsible for shutting the media. The main disadvantages of gate valve areas they work with time their disc damage due to the industries' vibration.
Non-Return Valve
These are types of valve that only allows and control media to flow to same or one direction. Its main advantage is that it may be installed to the condition where reverse flow is due to increased pressure or change in pressure. There are different kinds of non-return valves, and those are swing, clapper, and many more.
Air Logic Valve
Those are mechanical devices that are used to control the flow of air. It can be used in place of electrical control in incases where electrical power is impractical. Air logic valves are sometimes applied in the electrical pneumatic system, for example, the pilot valve and shot valve.
Ball Valve
Those are sunken ported spheres that swivel in the pipe stream for blocking or allowing the flow of liquid. The main advantage of a ball valve is that it can be practically applied in any liquid, whereby fluid flow must be shut off from a compression line to a high-pressure hydraulic system.
Butterfly Valve
These are mounted circular tips that swing into and out of the flow stream. The primary materials used to make this kind of valve are seal, seat, disc, and many more. Butterfly valves are used In wastewater plants to treat sewage before release into a central water body.
Check Valve
These valves perform the same duty as gate valves in that they control the flow of fluids in one direction or the same direction. They are made to be backed with springs that open under specific pressure and close as the pressure decreases. Hence those valves are suitable under high pressure.
These valves are mechanically used to control the flow of fluid through a given pipe .the piston valve mainly uses a cylindrical plug to close off, mainly used for isolation. The main tips to consider while designing a piston valve are the valve size, port connection, and the valve body's material. the main advantage of piston valve is that it may be used for isolation of different fluids
Summary
Under the types of valves are made in deferent particular ways of controlling the flow of different fluid under deferent pressure the maintenance of those valves gives it a long-lasting life span.
