Sporlan 278397-081 Valve
The Sporlan 278397-081, also identified by model QL171R-08-08, is a high-performance 1/2" ODF service valve designed for demanding air conditioning and refrigeration applications. Engineered with a robust brass body and PTFE packing, this front-seating shut-off valve ensures reliable leak-proof performance under high-pressure conditions up to 600 psig. Its primary role as a refrigerant service valve is to provide a secure maintenance point for charging, evacuation, and system diagnostics. The right-side access port is machined for a standard Schrader core, allowing technicians to perform pressure checks without interrupting system flow. Compatible with modern refrigerants like R-410A, this 1/2 inch ODF sweat connection valve operates across a wide temperature range of -65°F to 300°F. For contractors working in tight mechanical spaces, the compact QL series design and low torque requirements make it an essential component for residential and commercial split systems, heat pumps, and condensing units.
- Maximum System Integrity: The front-seating design with brass-to-brass stem seals provides a superior alternative to standard ball valves for long-term shut-off reliability.
- Heavy-Duty Construction: Built from forged brass to resist corrosion and mechanical wear in harsh field environments.
- Efficient Maintenance: Featured right-side gauge port facilitates rapid system evacuation and recharging via a standard 1/4" access fitting.
- Versatile Compatibility: Rated for a maximum working pressure of 600 psig, making it suitable for high-pressure R-410A and R-22 cycles.
- Compact Footprint: Specifically designed for HVAC service valve applications where clearance is limited.
Is the gauge port location fixed on the QL171R-08-08?
Yes, the "R" in the model number signifies a right-hand gauge port when viewed from the field connection. This orientation is critical for planning piping layouts in compact condensing units.
Can this valve be used for bi-directional flow?
As a front-seating shut-off valve, it is primarily used to isolate sections of the refrigerant circuit. While it can handle flow in either direction when open, it is typically installed on the liquid or suction line to facilitate service access.
What is the proper brazing procedure for ODF connections?
When installing the 1/2" ODF sweat fittings, technicians should use a wet rag or heat-sink paste on the valve body to protect the internal PTFE packing and brass-to-brass seals from excessive heat damage.
