When we look at piping and pumping systems externally, we generally see the set up as a whole rather than looking at its many working components individually. But there’s that one part that plays a very crucial role. They are the valves. They act like tiny knobs regulating the flow of fluids as well as cutting off supply completely if required.
Industrial valves are of diverse types, with each based on a different working principle and performing another function. Right here, we’ve discussed the 9 most frequent types of industrial valves. Check out online sources if you are really interested for buying valve .
- Ball valves – It is a hollowed out ball-shaped disc that is fitted inside a pipe. The valve starts and stops flow by the quarter turn rotational motion of this disk. When the valve is open the hollowed end is aligned in the direction of the flow and shut it sits perpendicular to the direction of the flow.
- Plug valves – Also called cock valve, it utilizes a cylindrical or tapered plug with a bored passage to block, begin or throttle flow. Turning the handle or wheel, arranges the hollow opening of the plug with the inlet and outlet ports opening the passage. It is blocked, once the good part aligns itself with ports.
- Butterfly valves – It’s still another valve that utilizes the rotational motion; ball and plug valves work in the identical way. It only uses a thin-disk from the flow path rather than a ball-shaped unit or a cylindrical plug. They are fast to use, extremely lightweight and easily adaptable.
A solenoid valve (also known as ” โซลินอยด์วาล์ว ” in Thai language)is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports.
- A wedge is inserted into a chair. With gate valves, the passageway can either be fully closed or fully open; there is no in between. They’re also called sluice valves.
- Globe valves – It is similar to a gate valve since it uses linear movement to throttle flow. It differs in its use of a disk rather than a wedge. It may also be adjusted to lower or increase circulation; the benefit of a globe valve is that it doesn’t leak as much as other valves. They’re also one of the most popular type of valves used across various applications.
- Pinch valves – The construction features a pinching mechanism and a sleeve of molded rubber or synthetic material. The flow path from the open position is unobstructed. The flow is cut off by pinching the flexible membrane, by lowering a pub or gate.
- Diaphragm valves – They work like pinch valves; a flexible diaphragm is inserted such that it fastens itself into the chair blocking the flow. Its advantage over pinch valves is that it generates an extremely tight seal and hence is used in applications with a high purity requirement.
- Relief and Safety valves – As fluids pass through the system, there’s a chance of an unprecedented rise in stress, which if unchecked could prove toxic. This applies especially if you’re dealing with hazardous fluids. Relief and security vales release pressure periodically, whenever it goes beyond the set point, to prevent damage.
- Check valves – Check valves permit unidirectional flow of fluids; they don’t let it flow back. The non-slam nozzle check valves assess pressure surge and prevent water hammer.
To ensure the valves fitted in your piping systems offer you the best service, you should buy them from a dependable industrial valve manufacturer. It is the only way to get top quality industrial valves that are designed to last.
