Where is the thermal expansion control valve located?Where is the thermal expansion control valve located?However, the thermal expansion control valve cannot be located where it is separated from the water heater by a stop valve nor by a pressure reducing valve, as doing so can prevent the thermal expansion control valve from safely sensing increased water pressure created by the water heater.Water Heater Thermal Expansion Tanks & Thermal Expanson wtv series temperature responsive expansion valves(plate) 4.2 Thermal expansion valves (TEVs) - SWEP

Adjusting The SuperheatingInfluence of Superheating on Evaporation TemperatureStabilityExternal and Internal Pressure EqualizationSizing The Thermal Expansion ValveSuperheating is the energy added to saturated gas, resulting in a temperature increase. During the evaporation of a liquid refrigerant, the temperature depends only on the boiling temperature of that refrigerant. Increasing the temperature (superheating) is possible only after obtaining 100% vapor.The spring inside the TEV acts on the needle to keep the valve closed if the TEV detects insufficient superheating. A minimum level of superheatSee more on swep.netTech Tips for Thermostatic Expansion Valves(steel) Dec 06, 2000Expansion valves are often suspected of causing system problems. But generally speaking, a TEV is operating properly if it maintains superheat of 5° to 15°. If superheat is low (lower than 5°), there is a potential for flooding refrigerant back to the compressor.(plate) C-WTV 4/10/02 11:42 AM Page 1 WATTS/Taras(steel) added benefit the 1170 series incorporates check valves in both the hot and cold water inlets to protect against cross flow.
