LENNOX 10W77 Corporation R-22 Expansion Valve

R-22 Expansion Valve

The 10W77 is designed to replace and/or upgrade older R-22 expansion valves without requiring any additional space, or voiding the system warranty.

The Lennox 10W77 Corporation R-22 Expansion Valve is designed for use with all standard air conditioning systems that still utilize R-22 refrigerant. The high quality polycarbonate body features a buna-N (Nitrile) gasket reinforced diaphragm to withstand extreme temperature fluctuations and pressures. It also boasts an aluminum heat exchanger to minimize size and weight, and reduce energy consumption.

The Lennox® 10W77 R-22 Expansion Valve is designed specifically to add refrigerant to cooling equipment and systems of air conditioners. This expansion valve is used at serial number 7005400 and above in air conditioning applications with a fixed orifice. These expansion valves are for use with R-22 Freon.

Our Lennox 10W77 is an R-22 expansion valve that is designed to allow a constant and steady flow of coolant through the lines. It is used to prevent excessive pressure buildup during extreme weather conditions or when a faulty component requires more cooling.

Used: The Lennox 10W77 expansion valve is used to automatically adjust the refrigerant flow in central air conditioning systems. It works in conjunction with your air conditioner's compressor and outdoor coil to maintain ideal levels of refrigerant in the system. This valve is designed for use with R-22 refrigerants, and features automatic control, low-pressure switch, a metal shaft, and over-charge protection.

The Lennox 10W77 Corporation R22 Expansion Valve is an expansion valve designed for single-stage heating and cooling systems. This expansion valve allows the refrigerant to escape faster or slower with changes in pressure, which increases or decreases refrigeration.

One valve, one part. Replace it all. Lennox Expansion Valves regulate the refrigerant flow to the evaporator during start-up and shut-down periods to prevent damaging overcharging and to ensure proper operation of the air conditioner or heat pump.
