Heatcraft Refrigeration 29311808 Expansion Valve Kit 1/3-C 3/8" X 1/2" ODF BBIVE

The Heatcraft Refrigeration 29311808 Expansion Valve Kit is a refrigerant flow control assembly designed to regulate the amount of coolant entering the evaporator. With a 1/3-ton capacity and 3/8-inch by 1/2-inch ODF connections, it is used in HVAC systems and refrigeration equipment to maintain proper pressure and temperature relationships throughout the cooling cycle. The valve responds to changing operating conditions to support optimized refrigerant distribution and heat absorption. As a key component within the refrigeration circuit, it supports efficient system operation, stable cooling performance and consistent temperature control in commercial applications.
