What’s the difference between a manual gas valve, an automatic valve, and a combination gas valve?
2025-08-25
There are three main types of gas valves used in modern gas appliances:
- Manual Gas Valve
– Operated by hand (e.g., a knob or lever)
– Simple and reliable
– Common in basic cookers, portable grills, or fryers
- Automatic Gas Valve
– Electronically controlled by a thermostat, timer, or sensor
– Enables precise temperature control and enhanced safety
– Ideal for ovens, heaters, and commercial appliances
- Combination Gas Valve
– An integrated system that combines multiple functions:
Gas flow control, Safety shutoff, Pressure regulation, Pilot or main ignition control
– Works with an ignition module to automatically ignite and monitor the flame, especially in fireplaces, water heaters, and furnaces
At Grand Mate, we offer all three types — including custom-designed combination gas valves built for seamless integration with ignition systems and certified to international standards like ANSI Z21.78, CSA, CE, or UL.
