Overview

ATX-12270DHS thermal expansion valve is a core throttling component engineered for HVAC and refrigeration systems, matched with R22 refrigerant and rated 43.5 tons cooling capacity. It adopts S-charged power head and 1×1 pipeline interface, precisely adjusting liquid refrigerant flow into evaporators by sensing evaporator outlet temperature. The integrated brass valve body features stable pressure resistance and outstanding heat conduction, which balances superheat of refrigeration circuits to prevent compressor liquid floodback, lift overall cooling system efficiency, and support continuous stable operation of medium-sized cooling equipment.

Key Features

43.5 ton standard cooling capacity, steady throttling performance for medium cooling systems
S-type charged power head, high sensitive temperature sensing response
Solid brass valve body, great pressure resistance and thermal conductivity
Standard 1×1 pipeline connection, easy installation and daily maintenance
Precise superheat adjustment, effectively avoid liquid slugging damage to compressors
Broad compatibility with multiple HVAC and industrial refrigeration equipment
