In industrial engineering, manufacturing and scientific communities, there is a vast use of valves. The main objective of the valve is to control the flow and pressure of water and to release air from the water system. Valves play a very ample role in the water industry. Water valves are used in many parts of daily mechanical devices such as HVAC and water system in an office.
Most Common Valves Found in the Water Industry and their Characteristics
1. Gate Valves
Gate valves are the most common valves found in the distribution system. Gate valves are mostly used for the on/ off control. Gate valves prevent the flow of the liquid in both directions. They are very easy to install and to maintain. Gate valves are cost efficient and they are mostly used in petroleum industries because of their abilities to cut through liquids.
2. Butterfly valve
Butterfly valve also known as quarter turn valve because it provides 90-degree rotary motion for stoppage. They often came in large sizes but short in length and are of very light weight. They posses very low torque requirements.
3. Ball Valves
Ball valves are considered as ideal for pump check services. In ball valves a ball rotates between two circular seats which are made up of a kind of PTFE and co- polymer. They exist in a small size range between 1/2” to 12”. These valves are used in higher pressure applications. Ball valves can be operated with less torque than gate valves and has small dimension and are lighter in comparison of gate valves.
4. Plug Valves
Plug valves are used to control the flow by rotating the conically tapered plugs inside the valve body. They came in a very simple design with few parts and their maintenance and repair is very easy to do. They contain very low head cost and comes drip tight closing.
5. Regulating Valves
Regulating valves are designed to enable the direct control of flow rate and the considerable control of process quantities i.e. reduces the flow/ pressure. A high head loss can be tolerated by regulating valve and they came with multiple control scenarios. These valves are installed on trunk or industrial pipelines and it consists of a regulating unit which varies the flow cross-section.
6. Air/Vacuum Release Valves
As it is clear from the name that these types of valves releases air during the filling and testing of pipe and it also releases air that naturally accrues in pipes. During draining it allows air into the pipe and it also assures the pipeline carrying capacity.
