What is lockshield ball valve mini

A lockshield ball valve mini, 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 lockshield ball valve mini is closed. It is controlled from the outside, often with a handle that is turned back and forth to open and close the lockshield ball valve mini.
Applications of lockshield ball valve mini                                                                      
Lockshield ball valve minis 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 lockshield ball valve mini

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

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

3. Confirm bore size of lockshield ball valve mini
There are three different types of lockshield ball valves mini:
1). Full bore lockshield ball valves mini 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 lockshield ball valves mini 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 lockshield ball valves mini, 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 lockshield ball valve mini
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 lockshield ball valves mini.

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

8. Confirm handle type of lockshield ball valve mini
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 lockshield ball valves mini smaller than 1”.
How to install lockshield ball valve mini                                                        
1. Before installing lockshield ball valves mini, 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 lockshield ball valves mini (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 lockshield ball valves mini 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 lockshield ball valve mini                                          
1. China/Global Market
HPb57-3, HPb58-3, HPb59-1, HPb59-3 are most common materials used for China lockshield ball valves mini, 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.

Surface treatments of lockshield ball valve mini                                                            
Surface treatments provide good protection to lockshield ball valves mini:
Rough color is brass valve body sandblasted and without plating.
Electroplating (nickel-plating and chrome-plating) can enhance the corrosion resistance of lockshield ball valves mini, increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance.
How we produce lockshield ball valve mini                                                                      
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 lockshield ball valves mini bodies.
4. The rough lockshield ball valves mini bodies are trimmed and cut off unnecessary parts.
5. The rough lockshield ball valves mini bodies are washed with sanding machines, to clean the dirty and oils during production.
6. The rough lockshield ball valves mini bodies are machined by CNC machinery for threads and dimensions.
7. The machined lockshield ball valves mini are nickel- or chrome-plated.
8. The brass valves are ready for delivery after final finished goods quality inspection.
