Temperature monitoring in factories or areas that produce heat requires several safety devices. One of them is a temperature limiting valve which can prevent excessive temperature from entering the system along with excess pressure and vacuum. The heating industry and technology always operate installations that already have this safe temperature limiter.
Heating installations will also use a combination of several control units in addition to temperature limiters. The temperature limiter will be on the upstream side consisting of a thermostat, safety temperature monitor, and temperature controller. When excessive heat occurs, the temperature limiting valve will open to divert the heat.
Then the closed loop and open loop control units will work to ensure the power plant can operate safely. This control function will work according to the time you have set. That’s when the system has reached the temperature limit you specified. The design for this safety temperature limiting valve will be by the mechanical temperature system.
Temperature detection according to the principle of liquid expansion. All installations that can generate heat must have a temperature-limiting valve as part of the safety device. There are standards that you must follow so that its use is always safe.

Temperature Limiting Valve on Water Heaters
Most water heaters are set between 120 to 140 degrees Fahrenheit. Lowering the temperature to 120°F can save up to 20% on heating costs. Temperature limiting valves ensure water remains at a safe temperature, preventing scalding.
Homeowners should set their water heater thermostats to prevent overly hot water. Advanced thermostats allow for automatic and remote temperature regulation. Gas water heater controllers typically have manual settings with labels such as HOT, VERY HOT, or LOW. Adjusting these settings can save energy and reduce heating costs.
Dimensions and Specifications of Temperature Limiting Valves
Temperature-limiting valves come in various dimensions and specifications. Generally, they feature a black ABS material hand wheel and a nickel-coated body. ABS (Acrylonitrile Butadiene Styrene) is a durable and versatile thermoplastic polymer used in various industries.
