Expansion Valve

EXPANSION VALVE -- This product is an expansion valve. The primary purpose of this product is to control the water flow rate through a heater.

Expansion valves are wall mounted 2-pipe devices, which have a concentric and exterior relief valve, and can be used on evaporative cooling packages to prevent over-pressurization.

The Lennox 31J32 Expansion Valve features a metal body, a 1/2" FNPT inlet connection, a 3/4" FPT outlet connection, and measures 5.75 Inch x 3.75 Inch x 2.00 Inch.

Expansion valves are designed to regulate the water temperature and pressure within a heat pump system. They allow the air conditioning unit to deliver temperatures below the ambient outside temperature without freezing, but above the boiling point of water (212°F). They also assist in preventing the air conditioning system from freezing during extended power failures.

Expansion valves are important parts to ensure that your gas furnaces operate efficiently. If you need to replace any, Lennox has you covered through convenient online shopping.
