Expansion Valves

Expansion valves regulate refrigerant flow and pressure in air conditioning and refrigeration systems, ensuring proper cooling performance and system efficiency. NWF Supply offers a selection of expansion valves, including Danfoss and Sporlan units, as well as OEM replacement valves for Lennox equipment.

These valves are designed to maintain accurate refrigerant metering under varying load conditions, and are selected to meet original equipment specifications for refrigerant type, capacity, connection style, and operating pressure. Properly matched expansion valves ensure optimal system performance, energy efficiency, and reliable operation.
