What is brass radiator valve

Brass radiator valve is a kind of brass valve that used house radiator, used to control temperature of radiator by adjusting the flow rate. Brass radiator valve is normally composed of a temperature controller (thermostatic head), brass valve body and connecting parts. The core component of brass radiator valve is the sensor unit, that is, the thermostatic head which can sense the change of the surrounding environment temperature to produce volume changes, drive the valve stem to produce displacement, and then adjust the water volume of the radiator to change the heat dissipation of the radiator. The setting temperature of the thermostatic valve can be adjusted manually, and the thermostatic valve will automatically control and adjust the water of the radiator according to the set requirements.In order to achieve the purpose of controlling the indoor temperature.

Applications of brass radiator valves

Brass radiator valves are mainly used for radiators of house heating system, one end of the radiator valve can be connected to the radiator pipe, the other end is connected to the radiator. There are 8mm radiator valves,15mm radiator valve, 22mm radiator valve; according to the operation mode, there are thermostatic radiator valve, manual radiator valve. We have diverse models and designs to meet these applications in a professional manner, you can choose a suitable radiator valve according to your own radiator.

How to select brass radiator valves

1. Confirm the functions of brass radiator valves

different functions and applications require different valves, for example, brass thermostatic radiator valves, programmable radiator valves, brass TRV radiator valves, brass angled radiator valves, brass corner radiator valves.

2. Confirm the working pressure of brass radiator valves

depending on pipeline pressure needs, the brass radiator valves are designed with valve wall thickness and port sizes. We have low pressure brass radiator valves, middle pressure brass radiator valve, high press radiator valve, super-high pressure radiator valve. Low and middle pressure brass radiator valve are mainly used for domestic and plumbing applications.

3. Confirm bore size of brass radiator valves

There are three different types of brass radiator valves:

1). Full bore brass radiator valve offers no flow restriction, which means that when it is open, the liquid can flow freely through it. This is achieved by making the ball larger than the passage size, so that the hole can be the same size as the passage.

2). Standard bore brass radiator valve does not have an oversized ball, and as a result, the hole is one size smaller than the passageway. This creates a small amount of flow restriction as the fluid passes through.

3). Reduced bore brass radiator valve, on the other hand, has an smaller ball and an even smaller hole, which creates significant flow restriction as the fluid passes through it.

4. Confirm thread type of brass radiator valves

Thread types differ from markets and applications: BSP threads for Europe and NPT threads for North America, also other metric threads, which you must confirm before buying brass radiator valves.

5. Confirm material type of brass radiator valves

We currently work with HPb57-3 brass radiator valves for most customers in Europe and Asia, CW617N brass radiator valves for Europe, C377700 and lead free brass for North America.

7. Confirm surface treatment of brass radiator valves

Rough brass color, nickel-plating, and chrome-plating are most widely used surface treatments for brass radiator valves. Plating helps to protect the radiator valves from oxygen and look shining.

8. Confirm handle type of brass radiator valves

C Generally three types of handle for brass radiator valves: 1. thermostatic head which works at set temperature automatically, 2. hand wheel handle which adjust manually, 3. lock-shield handle which operates by screwdriver

How to install brass radiator valves

1. Before installing brass radiator valve, clean and remove any objects from the pipes (in particular bits of sealing and metal), which could obstruct and block the valves.

2. Ensure that both connecting pipes either side of the valve (upstream and downstream) are aligned (if they are not the brass radiator valves may not work correctly).

3. Make sure that the two sections of the pipe (upstream and downstream) match, the brass radiator valve will not absorb any gaps. Any distortions in the pipes may affect the tightness of the connection, the working of the valve and can even cause a rupture.

Chemical compositions we use for brass radiator valves

1. China/Global Market

HPb57-3, HPb58-3, HPb59-1, HPb59-3 are most common materials used for China brass radiator valve, which are acceptable for most countries in the world, except for those customers have special requirements.

HPb57-3, also called China Normal brass, a variant of CW614N brass, is a local industry standard, with little Fe contents in composition, and lower costs than CW614N. It’s widely used as a standardized material in China and accepted by most global markets and customers.

HPb58-3, is a variant of CW617N brass and commonly used for brass radiator valves in China local market.

HPb59-1, has less Fe, Pb and higher price costs, it’s more used for high-quality products or market, such as brass fittings for USA market.

2. European Market

CW614N and CW617N brass materials are widely used for European brass radiator valves.

CW617N brass has better physical property to stand higher working pressure and temperature, more importantly the Pb percentage share is less than 2.5% and applicable for drinking water systems, good for environment and people’s health.

CW614N Brass is also popularly used because of similar compositions and lower costs, suitable for those applications without much environmental requirements.

3. USA Market

C46500 and C377700 are most widely used materials for USA brass radiator valves

As a requirement of AB1953 regulations, all the brass gate valve parts which contact the water shall have Pb content less than 0.25%, also called lead-free brass or no-lead brass, all the brass water valves for USA market, such as ball valves, brass gate valves, brass check valves, brass angle valves, have been compulsory to use lead free brass.

For those brass valves not for water use, such as brass radiator valves, heating valves, C377700, or China standard HPb59-1 brass materials are workable.

Surface treatments of brass radiator valves

Surface treatments provide good protection to brass radiator valves

Rough color is brass radiator valve body sandblasted and without plating.

Electroplating (nickel-plating and chrome-plating) can enhance the corrosion resistance of brass radiator valves, increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance.

How we produce brass radiator valves

1. Brass raw materials are bought from local suppliers in forms of brass bars.

2. Brass bars are cut into smaller pieces with different sizes according to order requirements, heated with natural gas.

3. The heated brass bars are forged by forging machines, Out-comings are semi-finished rough brass radiator valve bodies.

4. The rough brass radiator valve bodies are trimmed and cut off unnecessary parts.

5. The rough brass radiator valve bodies are washed with sanding machines, to clean the dirty and oils during production.

6. The rough brass bodies are machined by CNC machinery for threads and dimensions.

7. The machined brass radiator valve bodies are nickel- or chrome-plated.

8. The brass valves are ready for delivery after final finished goods quality inspection.

How we pack brass radiator valves

Brass radiator valve packing is very important for safe transport and brand appearance.

We pack brass radiator valves in small inner boxes, then put into outer cartons, finally load in wooden pallets.

It will protect the goods well and can avoid damages and wet.

We also pack as per customers' OEM designs.

How we test brass radiator valves

Our test laboratory equips with various devices for brass radiator valve quality inspect and control, as well as new product development.

Equipment include material spectrometer analyzer, flow rate tester, torque tester, body resistance tester, endurance tester, high-low temperature tester.

These equipment enable us to analyze brass radiator valve material compositions and type tests according to related standards, ensure our brass radiator valves are correctly designed and produced.
