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?
compensates for excessive evaporator pressure drop
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
Would a bimetallic strip work if the two different metals happened to have the same rates of expansion?
The one with the higher coefficient of thermal expansion.
What is thermal expansion and explain its two types?
- Thermal expansion is the dimension modification of a material under heating. - Linear, volumetric and area thermal expansion are known and measured for materials.
What are the two types of thermal expansion?
Linear, volumetric and area thermal expansion are known and measured for materials.
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.
What does an AC Receiver Drier do?
Ensures that only liquid refrigerant continues on to the Thermal Expansion Valve.
What is the purpose of an externally equalized thermal expansion valve?
compensates for excessive evaporator pressure drop
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 is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
Which component cosists of a thermal sensing element used to regulate the flow of liquid refrigerant into an evaporator?
Thermostatic Expansion Valve
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?
