Sporlan Controls 112778 3/8X1/2 R404A 1/2Ton Thermal Expansion Valve(Txv) ;5'Cap

The Sporlan Controls 112778 is a Thermal Expansion Valve, commonly known as a metering device, that is specifically developed for use in refrigeration and air conditioning systems using R404A refrigerant. This refrigerant is often used in medium-temperature commercial applications. The TXV regulates the flow of refrigerant throughout the system. By carefully managing the amount of refrigerant entering the evaporator coil, the TXV ensures optimal heat absorption and cooling efficiency. It operates by responding to changes in pressure and temperature within the evaporator. Due to heat absorption, the evaporator's pressure drops. This causes the TXV to slightly open, enabling additional ammonia to enter and restore the lower-pressure, colder state.
