Danfoss 8168027 Service Valve

The Danfoss 8168027 is a precision-engineered 3/8" service valve specifically designed for HVACR refrigeration units and high-pressure liquid line applications. Built for compatibility with most Danfoss reciprocating compressors, this valve features a robust rotolock connection that ensures a leak-proof seal under extreme thermal cycling. The sweat connection geometry is optimized for field brazing, reducing the risk of overheating internal components during installation. This HVAC service valve is rated for high-pressure refrigerants, maintaining structural integrity across a wide operating temperature range. As a critical refrigeration component, it facilitates technician access for system charging, evacuation, and pressure diagnostics. Its compact design allows for installation in tight mechanical cabinets without compromising the flow coefficient. For contractors performing sealed system repairs, the 8168027 provides the reliability needed for long-term system stability in commercial and industrial refrigeration environments.

• High-Pressure Tolerance: Engineered to handle high-PSI environments common in modern refrigerant cycles.
• Optimized Rotolock Interface: Precision-machined threads ensure a secure fit for compressor service ports.
• Superior Heat Dissipation: Designed to withstand standard brazing temperatures without valve seat distortion.
• Universal Compatibility: Fits a broad range of Danfoss MT and MTZ series compressors.
