What is a Thermostatic Valve? A thermostatic valve is a device that works behind the scenes to help achieve a desired temperature. It can be used for a range of purposes, such as maintaining a consistent temperature in a room or controlling the temperature output of water from a faucet or showerhead.

Thermostat The trick of the auto thermostat lies in the tiny cylinder at the engine-side of the device. The cylinder is filled with a wax that usually starts to melt at 180 F. A rod connected to the valve presses into this wax. And as the wax melts, it expands, pushing the rod out of the straw.

Thermal expansion valve Flow control, or metering, of the refrigerant is accomplished by use of a temperature sensing bulb, filled with a similar gas as in the system, that causes the valve to open against the spring pressure in the valve body as the temperature on the bulb increases.he condenser converts the high-pressure and-temperature gas to a high-pressure liquid by transferring heat to a lower temperature medium, usually ambient air. The high pressure liquid then enters the expansion valve where the TX valve allows a portion of the refrigerant to enter the evaporator.

Thermostat A thermostat is a component of a HVAC control system which senses the temperature of a system so that the system's temperature is maintained near a desired setpoint.he thermostat does this by switching heating or cooling devices on or off, or regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat may be a control unit for a heating or cooling system or a component part of or air conditioner.

EBME & Clinical Engineering Articles A thermometer is a device that measures temperature or temperature gradient. The word thermometer is derived from two smaller word fragments: thermo from the Greek for heat and meter from Greek, meaning to measure.or instance if the D:S ratio is 12:1, measurement of an object 12 inches away will average the temperature over a 1-inch diameter area. The sensor may have an adjustable emissivity setting, which can be set to measure the temperature of reflective (shiny) and non-reflective surfaces.

- TEMPERATURE ON/OFF CONTROL. On/Off control is the method of control used by most heating systems in the UK. The controls simply switch the current supplied to the boiler on or off at different times. The T6360 is a mains voltage Room Thermostat designed to give automatic temperature control of domestic wet central heating systems.

Thermocouple A thermocouple is a sensor for measuring temperature. This sensor consists of two dissimilar metal wires, joined at one end, and connected to a thermocouple thermometer or other thermocouple-capable device at the other end. When properly configured, thermocouples can provide temperature measurements over wide range of temperatures.

Thermostatic Expansion Valve or TEV 1) Reduce the pressure of the refrigerant: The first and the foremost function of the thermostatic expansion valve is to reduce the pressure of the refrigerant from the condenser pressure to the evaporator pressure.In the condenser the refrigerant is at very high pressure.The thermostatic expansion valve has a constriction or orifice due to which the pressure of the refrigerant passing through it drops down suddenly to the level of the evaporator pressure.s it is obvious from the above discussion the advantages of the thermostatic expansion valve are: 1) The TEV maintains the flow of the refrigerant to the evaporator as per the load inside. Thus the refrigeration or the air conditioning plant can run to the optimum capacity as per the requirements.

Technical Tidbits: The Technology of a Thermostat Thermostats regulate the temperature of the water in the cylinder block and help pressurize the system allowing rapid heat transfer from the cylinders to the cooling water. Most outboard motors use a similar system for cooling, regulating pressures, and maintaining correct engine temperatures.
