Angle Gas Ball Valve

Angle gas ball valve ART.N10112009 is specially designed for natural gas applications, better machining precision, better sealing parts, provide super safety to gas pipelines. Brass gas ball valve is a new 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.  

A angle gas 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 angle gas 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 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.

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 angle gas 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.

CW614N and CW617N brass materials are widely used for European angle gas ball valve.

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.

Rough color is angle gas ball valve body sandblasted and without plating.

Electroplating (nickel-plating and chrome-plating) can enhance the corrosion resistance of angle gas 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 angle gas ball valve bodies.

4. The rough angle gas ball valve bodies are trimmed and cut off unnecessary parts.

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

6. The rough angle gas ball valve bodies are machined by CNC machinery for threads and dimensions.

7. The machined  angle gas ball valve bodies are nickel- or chrome-plated.

8. The angle gas ball valve are ready for delivery after final finished goods quality inspection.

We pack angle gas 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 angle gas ball valves material compositions and type tests according to related standards, ensure our brass valves are correctly designed and produced.
