Description
The Heatcraft Refrigeration 29311817 Thermal Expansion Valve designed to control refrigerant flow into the evaporator for efficient cooling regulation. With 3/8″ x 1/2″ ODF connections, it is used in refrigeration and air conditioning systems to meter based on load conditions and evaporator temperature changes. In HVAC systems, it maintains proper superheat levels, preventing liquid from returning to the compressor and supporting stable cooling performance. It is installed in commercial cooling units and refrigeration equipment where precise control is required for consistent temperature management and dependable system operation during varying operating conditions.
