How to Choose the Gas Solenoid Valve for Commercial Kitchen Equipment
How to Choose the Gas Solenoid Valve for Commercial Kitchen Equipment
Posted:February 06, 2025
In a commercial kitchen, safety, and efficiency are very important, and one of the important components that guarantee both is the gas solenoid valve. This important device regulates the flow of gas to cooking appliances and thus the performance of these appliances. With so many selections to choose from, selecting the right gas solenoid valves can be difficult. We will make this decision easier by making some simple suggestions based on valve types and sizes as well as installation requirements. This guide is intended for both those who are managing an already established kitchen and for those who wish to start a new one, and it will provide a great deal of help in making an informed decision in ensuring the kitchen operates safely and effectively.

A gas solenoid valve is an electromechanical device used to control the flow of gas in different applications. It is made up of a solenoid (an electromagnet) and a valve body which either opens or closes to allow or prevent the flow of gas. Activating the solenoid will make a magnetic field which will push a plunger within the valve to a new position and the valve will allow or stop the gas flow. Gas solenoid valves are very important for safety and automation as they allow to control the of gas delivery with precision in different systems.
How does a gas solenoid valve work
The working mechanism of a gas solenoid valve is simple. Here’s how it operates:
Electromagnetic actuation: A magnetic field occurs as an electrical current passes through the solenoid coil. The plunger (or armature) within the valve is pulled by this magnetic field.
Open/close mechanism: Normally closed solenoid valves are open position: the valve is closed until electricity is applied. Upon energizing the solenoid, the plunger moves and pulls the valve seat upward as gas flows.
The magnetic field dissipates when the electrical supply is cut off and therefore the plunger returns to its original position sealing off the valve and the gas flow stops.
Common Applications Of Gas Solenoid Valves in Kitchens
There are many kitchen appliances and systems that utilize gas solenoid valves such as:
Gas boilers: Solenoid valves are used in gas boilers to control the flow of gas to the burners for efficient heating.
Cooking devices: Grills and Griddles use gas solenoid valves to control the delivery of gas to the flames to allow users to control the heat levels when cooking.
Gas stoves: The gas supply to each burner is controlled by solenoid valves in gas stoves that allow for precise control of cooking temperature and safe operation.
Key Factors to Consider When Choosing a Gas Solenoid Valve
When selecting a gas solenoid valve for your application, it is critical to consider several key factors to ensure optimal performance and compatibility.
Size of the valve: The size of the gas solenoid valve is very important to make it effective with particular appliances. The valve size has to be chosen correctly according to the gas appliance requirements. For larger systems that need higher flow rates, a 1 1/2 inch gas solenoid valve may be suitable, while smaller sizes may be used for household appliances or smaller installations.
Voltage requirements: Gas solenoid valves operate at different voltage levels, so it is important to know the requirements of your system. 12V DC valves are common in low voltage applications, for example in recreational vehicles and some home systems. A common 12V LPG gas solenoid valve is used for LPG systems and will provide reliable performance, while 240V AC gas solenoid valves are used in commercial applications.
Pressure and flow capacity: It must be compatible with the pressure and flow levels required for your application. The gas solenoid valve pressure drop is specified and should match the operating conditions of your gas system.
Durability: A gas solenoid valve must be reliable and durable to provide safe and efficient operation.
Types of Gas Solenoid Valves for Commercial Kitchens
By understanding the different types of gas solenoid valves, kitchen operators will be able to select the right valve for their needs.
Type
Description
Commercial kitchen gas solenoid valve
Made for a restaurant and catering appliance; it guarantees safe and efficient running of gas-fired apparatus like ranges, fryers, grills, and ovens.
Gas solenoid shut off valve
Automatically stops gas flow in case of malfunction or emergency; essential for emergency shut-off applications.
Gas boiler solenoid valve
Specifically designed for gas-fired boilers, it regulates the gas supply for heating equipment.
Normally closed valves
Gas only flows when the appliance is in use, making it safe to remain shut if no power is supplied.
Normally open valves
Used in processes where gas flow must be maintained until power is applied; maintains gas flow when no power is supplied.
Bi-stable valves
It can be turned on and off without continuous power, which is ideal for intermittent gas supply and saving energy.
2-port valves
They have two connections (inlet and outlet) and are commonly used to control gas flow to appliances.
3-port valves
An additional port for diverting gas flow from one outlet to another or for making a priority outlet for complicated systems.
Installation and Maintenance of Gas Solenoid Valve
Ensure you have all required tools, including wrenches, screwdrivers, and safety equipment (gloves, goggles). Obtain the appropriate gas solenoid valve that matches system specifications.
Turn off the gas supply: Before you begin the installation, turn off the gas supply to avoid leakages and ensure that the installation process is safe.
Locate the installation point: Identify where the gas solenoid valve will be installed in the system. It is usually near the gas supply line or on the appliance being controlled by gas.
Prepare the valve and connections: Check the new gas solenoid valve for any protective seals or packaging that needs to be removed and prepare the Valve and Connections. If the solenoid needs an electrical connection to operate, connect any electrical wiring.
Connect the gas solenoid valve: Install the valve on the gas supply line using appropriate fittings and make sure that all connections are secure and leak-free.
Check alignment: Verify that the valve is aligned properly as per the manufacturer’s installation instructions for proper operation.
Restore gas supply: Once installed, slowly turn the gas supply back on and check for any leaks around the connections with a soapy water solution or a gas leak detector.
Troubleshooting Gas Solenoid Valves
When dealing with issues related to gas solenoid valves, particularly when a solenoid valve is not functioning as expected, it is important to follow a systematic troubleshooting approach.
Gas solenoid valve not working:
Check solenoid power supply: Make sure the power supply to the solenoid is working properly. Check to see if wires and connections are damaged.
Test the solenoid: Check the continuity of the solenoid coil using a multimeter. If there is no continuity, the solenoid may be bad.
Inspect the valve for dirt or blockages: Remove the solenoid valve and check it for dirt or blockages that may prevent it from opening or closing.
Gas valve solenoid replacement:
If troubleshooting confirms that the solenoid is bad, carefully uninstall the old valve in reverse of the installation steps. Install the new valve according to the above.
Also, ensure proper electrical connections of proper fittings to prevent leaks.
It is important to choose the best gas solenoid valve for commercial kitchens to ensure safety and efficiency. Gas flow is controlled accurately, leak is prevented and accident risks are minimized by a suitable valve. Always follow the manufacturer’s installation instructions to get the best performance and safety.

FAQs
How can I determine the appropriate size of a gas solenoid valve?
To determine the correct size, consider the equipment's gas flow rate, measured in cubic feet per hour (CFH) or liters per minute (LPM). Match this flow rate to the valve's flow capacity. Also, check the pipe connection size to ensure proper installation without leaks or pressure drops.
What is the difference between normally opened & closed gas solenoid valves?
A normally closed (NC) valve remains closed when no power is supplied, only allowing gas to flow when activated. A normally open (NO) valve, on the other hand, stays open without power and closes when energized.
