What is brass mini ball valve

A brass mini ball valve, one type of quarter turn valve, is quite literally a ball placed in a passageway through which fluid flows. The ball has a hole through it, by which the valve opens and closes. When the ball is positioned so that the hole runs the same direction as the passageway, the fluid simply flows through it, and the valve is open. The ball can also be positioned so that the hole is perpendicular to the passageway so that the fluid cannot pass through, and the brass ball valve is closed. It is controlled from the outside, often with a handle that is turned back and forth to open and close the brass ball valve.
Applications of brass mini ball valves                                                                           
Brass ball valves have a wide application range, can be used different kinds of pipeline systems, for home and domestic water and gas supply, heating system, gardening and irrigation. We have diverse models and designs to meet these applications in a professional manner.

How to select brass mini ball valves

1. Confirm the functions of brass ball valves
different functions and applications require different valves, for example,  water ball valves, gas ball valves, sanitary ball valves, mini brass ball valves, PEX brass ball valves, tail brass ball valves.

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

3. Confirm bore size of brass ball valves
There are three different types of brass ball valves:
1). Full bore brass ball 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 ball 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 ball 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 ball 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 ball valves.

5. Confirm material type of brass ball valves  
We currently work with HPb57-3 brass ball valves for most customers in Europe and Asia, CW617N brass ball valves for Europe, C377700 and lead free brass for North America.

7. Confirm surface treatment of brass ball valves
Rough brass color, nickel-plating, and chrome-plating are most widely used surface treatments for brass ball valves. Plating helps to protect the brass valve from oxygen and look shining.

8. Confirm handle type of brass ball valves
Flat handle and butterfly T-handle are available, the flat handle (normally made of steel) have longer opening torque and is easier to open and close the brass ball valves; the butterfly handle (normally made of aluminum) is most used for the applications that have limited space to operate the handle, and most applied for brass ball valves smaller than 1”.
How to install brass mini ball valves                                                            
1. Before installing brass ball 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 ball valves may not work correctly).
3. Make sure that the two sections of the pipe (upstream and downstream) match, the brass ball 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 for brass mini ball valves                                            
1. China/Global Market
HPb57-3, HPb58-3, HPb59-1, HPb59-3 are most common materials used for China brass valves, 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 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 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 valves.

As a requirement of AB1953 regulations, all the brass 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 mini ball valves                                                                
Surface treatments provide good protection to brass ball valves:
Rough color is brass valve body sandblasted and without plating.
Electroplating (nickel-plating and chrome-plating) can enhance the corrosion resistance of brass ball valves, increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance.
How we produce brass mini ball 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 ball valve bodies.
4. The rough brass ball valve bodies are trimmed and cut off unnecessary parts.
5. The rough brass ball valve bodies are washed with sanding machines, to clean the dirty and oils during production.
6. The rough brass ball bodies are machined by CNC machinery for threads and dimensions.
7. The machined  brass ball 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 mini ball valves                                                                      
Brass ball valve packing is very important for safe transport and brand appearance.
We pack brass ball 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 mini ball valves                                                                            
Our test laboratory equips with various devices for brass 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 valve material compositions and type tests according to related standards, ensure our brass valves are correctly designed and produced.
