Full Bore Brass Gas Ball Valve

Full bore brass gas ball valve N10112001 is specially designed with o-ring stem sealing, which can prevent static electricity caused by handle opening and closing, provide better safety for flammable gas. Brass gas ball valve is a type of safety equipment for gas pipeline engineering, it is used to cut off, connect and adjust the gas in the pipeline, with good control characteristics and closing and sealing performance; suitable for city gas, liquefied petroleum gas, natural gas, Oxygen and other gas medium pipelines. 100% leakage test for each brass ball valve ensures reliable quality.  

Full bore brass gas ball valve, with big flow rate, 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 full bore brass gas ball valve.

different functions and applications require different valves, for example,  gas ball valves, hose gas ball valves, sanitary gas ball valves, mini brass gas ball valves, PEX brass gas ball valves, tail brass gas ball valves.

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

There are three different types of brass ball valves:

1). Full bore brass gas all 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 gas 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 gas 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.

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 gas 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.

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.

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.

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.

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.

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.

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.
