If you are talking about a temperature and pressure valve on a water heater (pop off valve). It is controlled by spring pressure and a rubber seal. As pressure in the tank increases the tension exerted by the spring on the rubber seal is over come until the point at which excess pressure is released around the rubber seal. When the pressure inside the tank decreases the spring again pushes the rubber seal closed. Temperature of the water in the tank is directly related to the pressure.. higher temperature = more pressure.

What is the purpose of an externally equalized thermal expansion valve?
An externally equalized thermal expansion valve is used to regulate the flow of refrigerant into the evaporator based on the evaporator's temperature. By sensing the refrigerant pressure at the outlet of the evaporator, the valve can adjust the flow rate to maintain proper superheat levels, ensuring efficient cooling performance in the system.
What is the increase of the volume of a substance by the increase of temperature called?
The increase in volume of a substance due to an increase in temperature is called thermal expansion. This occurs because as the temperature of a substance rises, the particles within it gain energy and move more, causing them to spread out and increase in volume.
The change in an objects volume that occurs when heat is added is called?
thermal expansion
What are not an example of thermal expansion?
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
What are the two types of thermal expansion?
Linear expansion and volumetric expansion are the two types of thermal expansion. Linear expansion is the increase in length of a material when heated, while volumetric expansion refers to the increase in volume of a material when heated.
Where is the expansion valve on blazer 1998?
The 98 Blazer doesn't have a Thermal Expansion Valve... it has a fixed orifice tube.
What is the function of expansion valve?
The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
Can a valve be installed at the end of steam expansion loop?
Yes. The expansion loop is only there to take up the thermal expansion of the pipe run, installing a valve will not impede the action of the loop.
Where do you find the Thermal expansion valve 2002 dodge ram 1500?
A 2002 Ram truck does not have an expansion valve. The ac system uses an orifice tube that is made into the liquid line.
What does an AC Receiver Drier do?
Ensures that only liquid refrigerant continues on to the Thermal Expansion Valve.
Which component cosists of a thermal sensing element used to regulate the flow of liquid refrigerant into an evaporator?
Thermostatic expansion valve consists of a thermal sensing element that regulates the flow of liquid refrigerant into an evaporator based on the temperature of the refrigerant returning from the evaporator.
What is the purpose of an externally equalized thermal expansion valve?
An externally equalized thermal expansion valve is used to regulate the flow of refrigerant into the evaporator based on the evaporator's temperature. By sensing the refrigerant pressure at the outlet of the evaporator, the valve can adjust the flow rate to maintain proper superheat levels, ensuring efficient cooling performance in the system.
What is the main part of car a.c?
COMPRESSOR, CONDENSER,EVAPORATOR, ORIFICE TUBE, THERMAL EXPANSION VALVE , RECEIVER-DRIER,ACCUMULATOR.
What things work because of thermal expansion and what things work because of thermal energy?
just wondering cause we are going over these things in class and i wanted to know what things work because of this?

The change in an objects volume that occurs when heat is added is called?
thermal expansion
Liquids expansion by heat?
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
