Application
The V48AM-2 is ideal for water-cooled condensers in commercial air conditioning and refrigeration equipment. The valve responds directly to refrigerant head pressure, opening or closing the condenser water circuit to maintain system pressures within the desired operating range. This helps protect compressors, improve energy efficiency, and extend equipment life. The union sweat connections simplify installation and future maintenance access.
