A Line-Up Of Different Valves Used In Water Supply Systems
There are a range of valves used in water supply systems that deliver a variety of operations. These valves regulate the flow of water and keep the pipeline in seamless conditions.Water supply valve is designed to withstand the diverse elements that might occur within the pipeline. Each of the valve types needs to be chosen with careful considerations.However, there are just too many valves that might confuse and keeping track of the functions, merits, specific design of each valve can be difficult. This is why to offer a thorough look of important valves used in water supply systems, we’ve prepared this list.In this article, you will find all the essential valves that are found commonly in water supply systems. Keep reading till the end to find out more.
Gate Valve
Gate valve is noted as one of the different types of water valves. This type of valve includes a gate type structure that acts as a metal block for water flow regulation. Raising the gate results in free flow of water whereas by lowering the gate, the flow can be stopped. This gate is controlled with a knob or a handwheel that is found at the top of the gate. It offers sealing for the pipes but is not designed to change the water flow route inside them.The major drawback of a gate valve is that the knob cannot indicate the opening or the shutting status of the valve. Also, gate valves are vulnerable to corrosion that might result in a stuck position of the valve.
Globe Valve
Globe valves are one of the water supply valves that works best in piping systems that fluctuates constantly. These are commonly used for applications where there is a requirement for limited or fastened water flow. Globe valves comprise a stopper that is designed to be lifted or lowered with the rotations of the wheel. Upon sealing of the baffle with the help of the stopper, the water flow is made to stop. The design of the globe valve contributes towards applications where the water flow needs to be restricted.
Check Valve
Check valves are mainly used when the flow of the water requires it to be maintained for one-sided flow. They are designed to regulate the flow within the pipe by using a ball-like element. If the water flows in the wrong direction, the ball works to stop the flow. In some of the check valves, there is a diaphragm with a rubber disc or rotating flap that delivers the sealing performance of the opening of the flow in the wrong direction.
Ball Valve
Ball valves are also noted among popular types of water valves. These valves are shaped similar to a sphere that rotates to direct the water flow. It allows shut off or fluid flow with the help of an opening present inside the valve. A handle design comes with the valve for opening or closing the valve. The valve is considered to be open allowing free flow of water when the pipe is in line with the ball valve’s hole. The valve is shut when the pipes are perpendicular to the sphere. The handle of the ball valve also functions as an indicator to show the valve’s status. Ball valves tend to shut at zero, 45, and 90 degrees and therefore, results in positive stops. This type of water valve is able to tightly seal the valve in the closed position.
Diaphragm Valve
Diaphragm valves are another valve that are used in water supply systems. These primarily are used for limiting the water flow within a piping system. They consist of a knob or a wheel for the valve to close or open the water flow. The knob or wheel is adjustable to the diaphragm for flow control. This valve has a design similar to the gate valve design. The sealing of the water flow route is carried out in the diaphragm valve when the diaphragm settles down on the saddle.
Butterfly Valve
Among the other components, the disc and liver are essential in a butterfly valve. The liver functions to control the rotation of this disc. Whereas, the disc is responsible for controlling the flow of water in the pipes. It is because of this disc, there is usually an occurrence of pressure drop in the butterfly valves. Butterfly valves are also able to create a perfect sealing result by using a gasket to cease the flow of water. There are also other types of category in this valve type such as a flanged butterfly valve, etc.
Needle Valve
This valve is best suited for use in water supply tubes. Even though needle valves are no longer permitted by building codes in several areas, the presence of these valves are still seen in a few homes which are also referred to as saddle valves. Needle valves are commonly used to attach a water supply tube to a water filter, refrigerator or other appliances. These operate by clamping onto a pipe and then pushing a hollow needle into the pipe for tapping the water.
A flexible plastic or copper supply tube is fastened to the fitting on the valve in order to bring water to the appliance. These valves are not considered to be dependable or reliable valve type, and they can vary in cost range widely. These are a few of the valves that are seen in diverse water supply systems.
