Residential and commercial properties rely on gas ball valves to deliver liquefied petroleum gas (LPG), natural gas, manufactured gas, and gas/air mixtures to gas equipment and appliances. Gas appliances such as boilers, water heaters, furnaces, fireplaces, and gas stoves also commonly rely on a ball valve.
Can you use a regular ball valve for gas?
Gas ball valves follow the same principles of other ball valves, they are mostly two-piece construction and feature a ¼ turn shut off. That being said, they are not your standard ball valve. Gas ball valves require CSA approval in order to be used in combustible gas applications.

Where can ball valves be used?
Ball valve is the most used fluid shutoff valve in upstream oil and gas production facilities, both onshore and offshore. They are also used in fuel gas systems feeding furnaces. Plug valves present the following advantages: Resistance to high pressure.
What is a natural gas valve?
A furnace gas valve is a component of your furnace’s fuel system. The furnace gas valve opens and closes, which allows the flow of gas to the pilot light and burner(s). … There are also gas valves located within gas-powered hot water systems or fireplaces.
What are valves used for in oil and gas?
Gas valves are flow control devices that play an essential role in any piping system. They are used in the oil and gas industry to handle, regulate and control the flow rates of gases such as natural gas, oxygen and liquefied petroleum.
What is a gas regulator?
A gas pressure regulator is a control device that maintains a defined pressure of a system by cutting off the flow of a gas or liquid when it reaches a set pressure. Pressure regulators come in several types and configurations and they provide control in a variety of applications in oil and gas processing.What is the most common type of valve used in gas operations?
Globe valves Conventionally used for isolation and throttling services, the globe has become the world’s most common types of valves.
What is fuel valve?A device which receives pressurized fuel as a liquid and sprays it into an engine cylinder as a fine mist. It consists of a nozzle and nozzle holder or a body. The nozzle has a series of small holes around its tip.
Article first time published onWhat ball valves are approved for natural gas?
The Apollo 80-100 Series is easily one of the best bronze ball valves on the market that is specifically designed for natural gas applications. The Apollo 80-100 is UL Listed for LP- Gas, natural gas, and flammable liquid and heated oil.
Will a natural gas valve work with propane?
Natural gas is a much lower pressure gas than propane and converting the appliance to one or the other gases requires that the differing pressure is compensated for. In other words, connecting a natural gas appliance to a propane piping system will result in appliance malfunction and possibly danger.
What color is a gas valve?
While a gas valve handle color is often yellow or red you will also find gas-rated shutoffs with valve handles in other colors such as green or blue. Plumbers don’t rely on the gas valve handle color.
What is a gas ball valve?
Gas cocks are shut-off ball type valves commonly used in installation of residential and commercial appliances and heating equipment such as gas stoves, fireplaces, water heaters, boilers, furnaces, etc. They are compatible with natural, manufactured, liquefied petroleum gas (LPG or propane) or air mixtures of such.
What are the advantages of a ball valve?
- They provide leak-proof service,
- Open and close quickly,
- Compared to gate valves, they have very small dimensions,
- Compared to gate valves, they are lighter,
- The multi designed flexibility does not exist in the Gate or Globe valve, and hence it lowers the amount of valves needed,
What is the difference between a ball valve and a gate valve?
The main difference is in the operation. A gate valve moves a solid disk up and down to open/close the orifice. A ball valve rotates a ball (the orifice) with a bore in it 90 degrees to open/close the valve.
What are gas valves made from?
Gas valves are made from metallic elements such as: Aluminum offers good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. Copper is ductile and malleable and one of the best conductors of heat and electricity. Both brass and bronze are copper alloys.
What is a flange oil and gas?
A flange is a projecting rim or collar on a pipe for a pressure vessel. When used in combination with another flange, it is capable of sealing a pressure vessel or another pipe. This is a reliable way of connecting pipe or vessel systems.
Which way do you install a gas valve?
When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing. When it’s turned a quarter turn, perpendicular to the incoming pipe, it’s closed.
Are gas shut off valves required?
The State of California requires approval for all excess flow gas shut-off valves and earthquake-actuated gas shut-off valves used within the state.
Which is the most commonly used and cheapest valve in industry?
Gate Valves Their simplicity allows them to be produced at relatively low cost, and with fewer parts than other valve types. However, their design makes them difficult to control precisely. Gate valves are most prevalent in the water industry.
What is a ball valve in plumbing?
Ball valves, also called shut-off valves, tend to be increasingly found in newer homes. Ball valves use a handle to control the placement of a hollow, perforated sphere in the mechanism. When the handle is turned, the hole immediately opens or closes the water flow.
What is a globe valve?
A globe valve regulates flow in a pipeline. It is used to control or stop the flow of liquid or gas through a pipe. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. … Globe valves are also known as throttle valves.
Do you need a natural gas regulator?
All natural gas grills are required to have an appliance regulator. It regulates the pressure going into the grill. It is good idea to have one on an LP grill that has high BTUs. These grills will include an appliance regulator that is convertible.
Do you need a pressure regulator for natural gas?
Gas grills are similar to gas stoves and fireplaces. They all need a regulator to work. During operation, natural gas passes through at 110 psi. The pressure that takes place is 10 pounds per square inch.
Are all natural gas regulators the same?
Gas regulators can be found in everything from an anesthesia machine to a car engine and are available in a wide range of settings and sizes. Regardless of the end use of a natural gas regulator, they all have the same basic operation.
Is fuel valve and fuel injector same?
When you step on your gas pedal, your vehicle’s throttle valve (which is a valve that opens and lets air into your engine) works in conjunction with your fuel injectors. When the throttle valve opens, your fuel injector sprays fuel to mix with the air and then enters the engine’s combustion cylinders.
Where is cylinder relief valve used?
A cylinder relief valve is a protective device fitted on top of the cylinder head that protects the engine and its surroundings from unprecedented damage from overpressure. It is one of the several-cylinder head mountings installed for the safe operation of an engine.
Are NIBCO ball valves rated for gas?
The NIBCO® bronze ball valve provides ease of operation with quarter-turn (90 degrees) open to close. The valve is designed to be used on gasoline, fuel oil, LP gas and other flammable fluids.
What does SWP stand for on a valve?
SWP: Steam Working Pressure: This designates the maximum recommended steam pressure a product can operate at. CWP: Cold Working Pressure: This designates the maximum non-shock pressure a product can operate at. “Cold” is generally defined as a range between -20°F to 100°F.
Does it matter which direction a ball valve is installed?
VALVE ORIENTATION: Ball valves may be installed in vertical or horizontal pipe runs, they are bi-directional therefore flow direction is not critical, however the best practice is to set up the valve handle to point in the direction of flow whenever possible.
