Types of Water Valves and How to Pick the Right One

Water valves are used in homes, businesses and utility industries to control the temperature and flow of water. Water valves have a variety of purposes, including controlling incoming water pressure, controlling hot water temperatures, and regulating the supply of water for several appliances or entire building systems.

Water valves are used to supply water to plumbing fixtures and equipment. They are usually installed in pipes that carry water from a water source to a sink or other fixture. Water valves can be opened and closed manually or automatically by an electric motor.

A water valve is a device that regulates the flow of water through a pipe to prevent excessive wastage or damage caused by overuse. It usually consists of two moving parts: an inlet valve, which controls how much water enters the pipe; and an outlet valve, which controls how much water leaves the pipe. The flow rate through the valve can be adjusted by turning one or both handles on each side of the handle assembly. The handle assembly can also be controlled by an electric motor if it has been fitted with one.

You Should Know About Water valves

Water valves are often fitted with safety shutoff features that allow them to be used for small amounts of time without causing large amounts of damage when they are accidentally left open for long periods or when there is not enough pressure in the pipe system to open them fully automatically.

Any water utility system would be incomplete without valves, which provide a number of functions including halting and beginning flows, permitting flows solely in one direction, lowering pressure, relieving pressure, and regulating pressure. These are only a few of the water system valves’ most important applications.

What is the purpose of water valves?

Water valves control the temperature and flow of water through pipelines and plumbing fittings. The valves regulate steady flow and volume when they are placed and used correctly. Brass, plastic, stainless steel, bronze, cast iron, and galvanized pipe are among the materials used for water valves.

Water valves are used in a wide variety of applications. They comprise two main parts: a control mechanism, which engages the open position when opened, and a valve seat, which sits against the control mechanism to keep the valve closed.

Different Types of water valves

Water valves are used to control the flow of water through pipes. There are many different types of water valves which can be used to control the flow of water. These include:

路   Simple Bell Valve

This type of valve is normally used when there is a single pipe that needs to be controlled. It has two positions, closed and open. A simple bell valve can be connected directly to a pipe, or it can be connected to a pressure gauge or pressure regulator.

路   Stem Ball Valve

This type of valve is normally used with two pipes, one above the other. It has three positions, closed, half open (called 鈥榗heck鈥), and fully open (called 鈥榬eturn鈥). The stem ball valve must be used in conjunction with a check valve, another type of valve that prevents back jetting when the stem ball valve is opened fully.

路   Gravity Ball Valve

This type of valve works by relying on gravity alone to control the flow of water through its pipe. It has only two positions, closed and open. Gravity ball valves are commonly found in residential homes where hot water systems are being installed as part of new construction projects or renovations

路   Compressed air valves

Compressed air valves are introduced in the compressed air system to control the flow of compressed air.

They are divided into two types

路         pressure regulator

路         pressure switch.

Pressure regulators can be connected with cylinders or tanks to regulate the pressure. The regulator is connected at its outlet with a gauge. If the pressure exceeds a predetermined value, it will close automatically and stop supply of air to the cylinder or tank.

Pressure switches are used as an alternative method of preventing over-pressurization of cylinders or tanks by regulating the flow of compressed air on demand. A pressure switch consists of two parts: a float and a diaphragm. When the float rises due to excess water level in tank or cylinder, it blocks off normal supply of compressed air; hence closing of valve is possible only when there is no water present in tank or cylinder.
