Have you not found a trusted valve producer in China interested in buying a new natural gas ball valve? The ranking of many suppliers is rapidly growing, and a steady increase in the number of natural gas ball valve manufacturers has been observed during the last few years.
What is a Gas Ball Valve?

A gas ball valve, called a quarter-turn valve, applies a hollow, perforated ball as the closure element. It works by opening or closing a cavity or port in the ball’s center to regulate gas flow. The valve opens when the ball is aligned with the pipes, allowing gas to pass through. When the ball is turned so that it is perpendicular to the flow path, the valve closes, thereby blocking the passage of the gas. Gas ball valves are used in pipe systems to get fluids like LPG, natural gases, hydrocarbons, and chemical lubricants. The valves can efficiently manage fluid flow in systems supplying residential, commercial, or industrial usage.

Steps for Choosing a Natural Gas Ball Valve
Consider the Gas Appliance Regulation (GAR) rules when choosing a gas ball valve. Like any other ball valve, the gas must meet the system’s pressure, temperature, and fitting arrangements standards. When choosing a gas ball valve, you should also think about a few other things, which we’ll talk about below:
Flow characteristics:
In the system, think about how the gas flows. Some gases may have uneven flow or contaminants or particles in them. To keep the gas flowing smoothly, choose a gas ball valve with a design that reduces flow disturbances. This could be a full port design or one of several unique trim options. These features or changes to the valve’s internal parts improve flow characteristics and lower turbulence.
Gas ball valve leakage classifications:
Gas ball valves are put into groups based on how often they leak. API 598 and ANSI/FCI 70-2 are two frequently used classes.
- API 598 groups out six levels of leakage rates, from Class I (no obvious leakage) to Class V (allows large leakage).
- ANSI/FCI 70-2 adds a more exact classification system, with Classes I through VI. Class VI has the tightest shutoff and the least amount of leaks.

Materials:
Gas ball valves can handle high pressure and temperatures. The leakage of fluids must be stopped at all costs since most working fluids can catch fire. These gas ball valves are made of metal or PTFE to keep fluids from leaking. People often make a gas ball valve body from aluminum, copper, stainless steel, or brass.
Design:
There are two types of gas ball valves: those with a moving ball and those with a trunnion-mounted ball. Floating ball valves utilize the fluid’s pressure to seal the ball and seats together. Mechanical fixing of the ball at the top and bottom of trunnion-mounted ball valves lets them handle higher pressure and bigger uses while still closing well.
Cavity relief mechanism:
A cavity release device is often built into gas ball valves to keep the valve cavity from building up too much pressure. This system part usually has a small hole or vent ahead or behind the ball. It removes any fluid stuck in the hollow, which lowers the chance that the valve will break or stop working.
Compliance with industry standards:
The American Gas Association (AGA), the American Petroleum Institute (API), and the International Organization for Standardization (ISO) establish specific industry standards and regulations that gas ball valves are designed and manufactured to comply with. These factors may comprise standards for intrinsically safe or explosion-proof design, fire resistance, or safety certifications.
Frequently Asked Questions About Natural Gas Ball Valve
Can a gas ball valve be used for water?
Although gas ball valves are predominantly intended for use with gases, they can also be employed in water applications in certain circumstances. The valve’s material compatibility, pressure and temperature ratings, and any applicable certifications or standards for water applications should be considered.
How do you evaluate the quality and performance of a gas ball valve?
Assess the quality of the product by examining the manufacturer’s industry certification and standing and adhering to a variety of standards by API, ANSI, ISO, and other relevant organizations.
Check the technical specifications for information on the materials, design features, pressure and temperature ratings, and anti-static and fire-safe options. Consider the warranty terms and how the ball valve manufacturer will offer post-sales assistance.
What is the temperature and pressure range of the gas ball valve?
Brass gas ball valves are extremely adjustable and can operate within a temperature range of -10˚C to 120˚C. Conversely, brass gas ball valves are rated at 600 psi or higher in terms of pressure. This renders them appropriate for residential and specific industrial environments. Nevertheless, the range of this product is up to 125 PSI for natural gas applications.
What are the uses of gas ball valves?
In combustible gas applications, gas ball valves provide dependable performance and efficiently regulate air, gas, and condensate passage. Gas ball valves are used in residential and commercial properties to supply equipment and appliances with liquefied petroleum gas (LPG), natural gas, manufactured gas, and gas/air mixtures.
A ball valve is also frequently employed in gas appliances, including boilers, water heaters, furnaces, fireplaces, and gas ovens.
What is the difference between a gas ball valve and a standard ball valve?
Gas Ball Valves are frequently constructed from materials resistant to specific gases’ corrosive properties to regulate and control the passage of gases. Common materials include stainless steel, brass, and occasionally PVC. The seals of these devices are also intended to prevent the leakage of gases, which can pass through small spaces that liquids cannot. Nevertheless, a standard ball valve may be intended for general use or liquids in particular. The materials selected may differ significantly based on the application, including brass, stainless steel, and PVC.
