Overview

The ATX-12420DHS thermal expansion valve is a core throttling component designed for HVAC and industrial refrigeration systems, compatible with R22 refrigerant and rated for 67.6 tons cooling capacity. It adopts S-type power head charging and 1×1 pipeline connection design, which accurately regulates liquid refrigerant flow into evaporators by sensing evaporator outlet temperature. The solid brass valve body delivers stable pressure resistance and reliable heat conduction, precisely balancing refrigeration loop superheat to prevent compressor liquid floodback, boost overall cooling system efficiency, and sustain long-term stable operation of large-scale cooling equipment.

Key Features

Large 67.6 ton cooling capacity, stable throttling performance for heavy-duty cooling systems
S-charged power head with high-precision temperature sensing response
Full brass valve body structure, excellent pressure resistance and thermal conductivity
Standard 1×1 pipeline connection, simple installation and maintenance
Accurate superheat adjustment, effectively avoid liquid slugging damage to compressors
Wide compatibility with various HVAC and industrial refrigeration equipment
