Valves in pipe lines are provided to control supply of water. They are used to stop supply when any repair is carried in pipe line. Valves are devices that control the flow of fluids and gases. Some are used to regulate the rate of flow, and others are used to stop it completely to prevent flooding or allow repairs to be made.

There are dozens of different types of valves, and each performs a specific task. But there are many other valves used in the typical residence.

Compression valves are found out in a two handle faucet, one for the hot water and one for the cold water. In order to control the pressure of your water, compression faucets use a system of seals and washers. At the bottom of the stem it consists of a rubber seal. It presses against the valve seat to block the water flow. Turning the handle the other way releases the seal against the seat and the water flows.

When a compression type stem springs a leak it is usually because its washer, located at the tip, has worn out, allowing water to seep between it and the faucet’s seat.

Cartridge valve also known as “washer- less” valves, and are controlled by only one handle, in contrast to compression valves. Cartridge valves use a single cylindrical cartridge made of either metal or plastic, which rests inside the faucet body. When the valve handle is lifted, the valve stem raises and its holes align with the holes of the cartridge. Leaks around the base of the cartridge are usually caused by corroded O-rings.

Disk valves are also without the washers. They are used mostly in single-handle kitchen sink faucets. These are also cylindrical in shape and are present in the faucet. This type of valve uses ceramic disks which fit exactly against each other, with every disk having a series of holes. It comprise of two hoses, one each for the hot and cold water.

Ball valve is an automatic flow control device. Regulating principle is the level of some free water surface. Ball valves basically consist of one handle under which a cylindrical cap is located. As the valve handle is turned to open the valve, the ball rotates to a point where part or the entire hole through the ball is in line with the valve body inlet and outlet, allowing fluid to flow through the valve.

Repairing valve: Leaking water valve is the most common plumbing problem within the home. Thus, repairing valves are highly prone to leaks. However, these can be repaired very easily.
