Some Useful Facts Related With The Gas Valves
A gas valve is an apparatus that takes control of gases like liquid propane or well usual gas. These are used for numerous applications. These are obtainable in a huge number of outlet ports, inlet, sizes flows as well as pressure ratings. Gas valves are normally manufactured of plastic such as polytetrafluoroethylene, chlorinated polyvinyl chloride, polyvinyl, or metallic elements like brass, bronze, steel, iron, aluminum, copper.
Three Types of Gas control valves
Gas control valves or gas valves are used in a number of common family appliances, like water heaters, cooking stoves and space heaters. The three most usual kinds of gas valve come with a single thermocouple. Moreover, there is a thermopile in the ODS systems as well as in thermocouple.
Thermocouple is the normal element in the gas valves. This part uses the difference of temperature at the end of two pieces of metal to make a little bit of electrical charge. Voltage is generated by the thermocouple that activates an electro magnetic coil. On one occasion, the coil opens and lets the gas to run to the burners, as it gets activated.
The Thermopile System
A system of gas valve takes in most part of the thermopile rule. As well, the thermocouple that activates the flow of gas, a thermopile puts in an extra functionality to the machine. A thermopile takes in a range of thermocouples that endow with enough electrical charge. The thermopile integrated into a system that produces a three hundred to six hundred mill volt signal, which could be used by a thermostat to release the major gas control valve in the device. Such kind of system is commonly used to the household appliances like hot water tanks and heaters.
To begin this procedure, let the gas flow direct to pilot of the heater. Keep in mind that one end of the thermocouple need to be heated. Let the gas flow in spite of a slow thermocouple heating. A good number gas valves have a bypass switch to allow lighting of the pilot at what time the thermocouple is quite cold. Later than thirty seconds, the bypass can be opened and the flow of gas must be carried on. Handling a single-thermocouple system is quite trouble-free. More often than not, it is only used in little gas-powered heaters.
The ODS Valve
The most consistent and secure type of gas valve is the ODS valve that stands for the oxygen depletion sensor. This kind of gas valve has an interior sensor, which measures the quantity of oxygen in the in the air. If you want to get an ideal as well as affordable gas control valve, then you need to go for the efficient Honeywell gas valves.
