Can you also use a ball valve for gas?

A gas valve has the AGA (American Gas Association) symbol on it cast the valve body. If it doesn’t have the symbol, don’t use it for gasoline. Some valves are marked WOG (water, oil, or gas).

Additionally, what types of natural gas valves are there?

The Apollo 80-100 is UL listed for LPG, Natural Gas and flammable liquids and heated oil. This two-piece bronze ball valve comes standard with a blowout proof stem and is designed to withstand a maximum pressure of 205 PSIG in temperatures up to 460F. For natural gas, it’s a natural choice.

Similarly, you may be wondering what is a gas ball valve?

Gas ball valves. Gas ball valves are similar to regular ball valves but are designed to withstand the pressures of commercial and industrial gas applications. Our gas ball valves are all 100% leak tested and made in Italy.

What color are gas shut off valves?

While the handle color of a gas valve is often yellow or red, you will know you can also find gas shut-off valves with valve handles in other colors such as green or blue.

Where should a gas shut-off valve be placed?

The gas meter and gas shut-off valve are usually located on the side or in front of the building . If the building has a wind tunnel, it might be there.

How to test a thermocouple?


  1. Locate the pilot light control on the gas valve.
  2. Turn on the pilot light for 30 seconds.
  3. Release the button to see if the pilot light goes out.
  4. Turn off the gas supply to test the Thermocouple again.
  5. Count to 20 and wait for the indicator light to go out.
  6. Listen for the click near the gas valve.

What does a gas valve look like?

Homes using natural gas have a main shut-off valve (Fig. A) just before the gas meter. This valve, often referred to as the street-side valve, is usually a rectangular nub (Photo 1). When the long side of the knob or handle is parallel to the gas supply line, it is open and gas is flowing.

What types of valves are there?

Different types of valves are available: Gate valve, globe valve, plug, ball, butterfly valve, check valve, diaphragm, pinch valve, pressure relief valve, control valve, etc. Each of these types has a number of models, each with different features and functional capabilities.

What is a gas valve used for?

The stove’s gas valve controls the flow of gas to the main burner, sometimes to a pilot burner as well. Modern gas valves may also have a built-in controller that verifies the safe operation of the furnace by “detecting” ignition and providing a 100% shutdown in the event of a failure.

How do I free a stuck gas valve?

With the pump running and AFTER hearing the solenoid “click”, GENTLY tap the gas valve body a few times with a soft mallet or a piece of wood. This CAN loosen the valve if it is stuck.

How much does a gas control valve replacement cost?

Gas control valve replacement – $300 to $500. If your pilot light and thermocouple are in good condition, you may need a new gas control valve. If this part has failed, a replacement is usually a more efficient and less expensive option than repair.

What valves are used for throttling?

The two main types of valves used for throttling applications we offer our seat valves and our needle valves. With both of these valve types, a stem is raised and lowered into the flow path and can be stopped at any point and left in that position.

How do I choose a valve type?

Choosing the Correct valve means matching the size of the valve to the expected flow through the system. Know the chemical compatibility requirements. The materials of the valves must be compatible with the gases or liquids flowing through. Plastic valves typically resist harsh or caustic chemicals better than metal valves.

How do I turn off the gas to my house?

Runs parallel to the pipe , usually about 6 to 8 inches above it Floor. Take a 12″ or larger adjustable wrench and turn the valve 1/4 turn in either direction until the valve is perpendicular to the pipe.

How do you test a gas valve?

How to check the oven’s gas valve with a multimeter

  1. Turn off the oven at the wall control.
  2. Using a screwdriver, remove the screws in the service panel on the side of the oven.
  3. Disconnect the wires from the gas valve terminals.
  4. Set the test dial on the multimeter to “mV” which stands for millivolts.

What causes a gas valve to break?

There are several reasons why this valve stops working properly. The valve itself may simply be worn out or damaged from basement seepage or submersion. Alternatively, one of the electronic gas ignition components or a fault in the safety circuit may be to blame.

How do you know if you have a bad thermocouple?

If you can’ If the flame doesn’t ignite at all and sure the throttle is on, there is probably an obstruction in the pilot tube. If the flame ignites and goes out when you release the gas control button after holding it for the recommended 20 to 30 seconds, that is a sign of a thermocouple malfunction.

What is the difference between a gas valve and a water valve?

This stands for water, oil or gas. Most gas valves are made of brass and are much heavier than standard valves. The other difference is that most gas valves open or close with a quarter turn. Ball valves also work in the same way. Using a gas valve for water is better than using a water valve for gas.

Why do gas valves fail?

A diaphragm connected to a valve controls gas flow and pressure. A thermocouple senses the heat of a pilot flame and generates a current that keeps a solenoid valve open. Gas valves can fail for a variety of reasons including contamination, product defects and misuse.

What are gas valves made of?

Gas valves are made of metallic elements such as : Aluminum provides good electrical and thermal conductivity , high reflectivity and oxidation resistance. Copper is ductile and malleable and is one of the best conductors of heat and electricity. Both brass and bronze are copper alloys.

How do I know if my gas line is open?

These valves make it easy to tell if they are open or closed. In the open position (gas is flowing) the handle (lever) is parallel to the tube, in the closed position (no gas is flowing) the handle (lever) is perpendicular to the tube. This should make it easy for you to tell if the throttle is on or off.
