Internal Valve Types For Washbasin Faucet

The internal valve of the wash basin tap is a key component in regulating the flow of water from the faucet. It is responsible for controlling the water flow, shutting off the water supply, and maintaining the water temperature.

The most common types of internal valves found in lavatory faucets are compression valves and ceramic disc valves. Compression valves are the traditional type of valve found in older faucets. They consist of two rubber washers that press down on a metal seat to stop the water flow. When you turn the faucet handle, it lifts the valve stem, pushing the gasket onto the valve seat, which stops the water flow. Gaskets can wear out over time, causing leaks and reduced water pressure. The compression valve is relatively easy to replace, and replacement gaskets are readily available.

A ceramic disc valve is a more modern type of valve that uses two ceramic discs to control the flow of water. The two discs fit together and move against each other, creating a watertight seal. When you turn the faucet handle, the discs separate allowing the water to flow. Ceramic disc valves are more durable than compression valves and can last for years without replacement. They also provide smoother and more precise water flow and are less prone to leaks.

To maintain the internal valve of the lavatory faucet, regular cleaning is essential. Over time, mineral deposits in the water can build up on the valve, causing it to become clogged or damaged.
