Carrier 32GB402544 7/8″ 30-Ton Electronic Expansion Valve for Brine

Description

The Carrier 32GB402544 is a factory-engineered Electronic Expansion Valve (EEV) designed for large-capacity commercial HVAC and refrigeration systems operating with brine (glycol-based) secondary coolant circuits. With a 7/8″ connection size and a rated capacity of 30 tons, this EEV delivers precise, electronically controlled refrigerant metering to optimize system efficiency, protect compressors, and maintain stable superheat across a wide range of operating conditions.

Electronic expansion valves offer significant advantages over traditional thermostatic expansion valves, including faster response to load changes, tighter superheat control, and compatibility with modern DDC and BAS control platforms — making this valve an ideal replacement or upgrade component for Carrier commercial chillers and large-tonnage cooling equipment.
