Nissens 999320 Air Conditioning Expansion Valve

The Nissens 999320 is a thermal expansion valve (TXV) designed for air conditioning systems. This precision metering device controls the amount of refrigerant released into the evaporator, maintaining optimal superheat conditions and ensuring maximum AC system performance.

Key Features:

• Block-type valve technology with thorough welding process to eliminate refrigerant leaks
• Comprehensive testing for pressure performance, tightness, opening characteristics, and set-point accuracy
• Outlet and operating pressure tested to OE matching standards
• Includes O-rings and mounting hardware when applicable
• Manufactured to strict quality standards with rigorous validation testing

Nissens expansion valves are engineered to maintain proper refrigerant parameters throughout the AC cycle, ensuring optimal thermal performance and system balance. The valve separates high-pressure and low-pressure sides of the AC system while contributing to proper compressor lubrication by ensuring sufficient refrigerant flow. Each valve undergoes extensive performance testing to guarantee stable function within the full range of refrigerant temperatures and pressures encountered during normal operation.
