Sporlan 278395-061 Valve

The Sporlan 278395-061 is a professional-grade QL171R-06-06 3/8" ODF service valve engineered for critical refrigeration and air conditioning system isolation. Built with a forged brass body and stainless steel trim, this front-seated shut-off valve provides a reliable seal to manage refrigerant flow during system maintenance or evacuation. Unlike standard steel valves, the brass-to-brass stem seal and corrosion-resistant construction ensure a leak rate of less than 1/10 ounce per year, maintaining system integrity even under high-pressure conditions up to 600 psi. This specific Parker Sporlan valve features a right-side Schrader valve fitting (gage port), allowing technicians to perform pressure checks or charging without disrupting the main line.

Installation is streamlined via extended copper connections designed for 3/8" ODF sweat fittings, protecting the internal synthetic components during brazing. The low pressure drop porting and tamper-proof recessed stem drive make it a preferred choice for contractors seeking a refrigeration service valve that minimizes turbulence and energy loss. Whether utilized in commercial split systems or residential units, the QL171 series provides the precise control needed for refrigerant recovery and system isolation.

• Forged brass construction delivers superior durability and eliminates the rust issues common with steel alternatives.
• Integrated Schrader port on the right side provides easy access for pressure monitoring and HVAC technician service tasks.
• Tight stem sealing with a front-seating design ensures zero-leak performance during system isolation for evacuation and charging.
• 3/8" ODF sweat connections allow for direct brazing into the line without the need for additional adapters.

Is this valve compatible with modern refrigerants?
Yes, its high-quality brass and synthetic materials are compatible with most common refrigerants, though always check for system pressure limits.

Can I braze this valve directly without disassembly?
While the extended copper fittings are designed to pull heat away, it is best practice to wrap the valve body in a wet cloth to protect internal seals during high-temperature brazing.

Which side is the gage port located on?
The "R" in the QL171R-06-06 model number indicates that the service port is located on the right side when looking directly into the field connection.
