Choosing a 15mm Stop Valve For Your Central Heating System

If you're looking for a 15mm stop valve to install in your central heating system, you'll find a wide range of options. These include the Prestex compression fit 15mm valve, the  white plastic stop valve, and the Brass stop valve. But remember: these valves are not suitable for drinking water.

A compression fit 15mm stop valve is a versatile and reliable plumbing fixture. This brass stop valve is easy to install and comes with a five-year manufacturer's guarantee. It is suitable for both domestic and commercial applications. The spherical closure unit inside the valve opens and closes when the lever is pulled.

The white plastic 15mm stop Valve is designed for quick and convenient in-line shutoff and shut-off protection. The valve is available for both hot and cold water applications. The valve is easy to install, and is a popular choice for contractors and homeowners alike.

This valve is a push-fit design that connects copper or plastic pipe. Its two  connections allow you to quickly and easily shut off water to a fixture. The valve is lead-free and non-toxic and is easy to install and demount. It is suitable for hot and cold water systems, and is certified to BS EN ISO9001 and BSI Kitemark.

This valve has a 15mm x 20mm diameter and is available in both standard and emergency shut-off options. It is suitable for most plumbing projects. This valve is also available with an ESOTP angle service valve. It is easy to install and features an integral pressure relief valve to prevent overflow.

Using brass for drinking water valves is a traditional practice, but this material may not be the best choice for your home. While it is highly machinable, brass and its alloys contain lead, which is highly hazardous to human health. Thankfully, many regulations have been established to help make drinking water lead-free. For example, the EPA limits the amount of lead that can be present on a drinking water valve to 0.25% of its wetted surface area. As a result, manufacturers and contractors are required to calculate the lead content of a drinking water valve. Fortunately, there are now lead-free brass valve options available.

Generally, brass solenoid valves are a good choice for most plumbing systems. They come in two basic forms: leaded and non-leaded versions. The non-leaded variety is better suited for drinking water systems. Though it may not be as reliable as other valve types, brass solenoid valves are a relatively inexpensive and effective alternative for your plumbing system.

Another type of valve is made from carbon steel, also known as low-alloy steel. This material is a combination of carbon and iron, along with other alloying elements. Carbon steel is available in different grades, which differ in hardness and malleability. Mild and medium range carbon steels have medium carbon content and are malleable enough to be customized for specific applications.
