Sporlan 278399-121 Valve
The Sporlan 278399-121, model QL171R-12-12, is a high-performance 3/4" ODF service valve designed for rigorous HVACR applications. Built with a heavy-duty brass body and a stainless steel stem, this manual shut-off valve provides reliable refrigerant isolation during system maintenance. It features a robust Buna-N seal to ensure leakproof integrity across a wide operating range of -40°F to 250°F. Engineered for modern high-pressure systems, the Parker Sporlan QL valve is rated for a maximum pressure of 600 PSI, making it fully compatible with R410A refrigerant and other common synthetic oils. Its 3/4 inch ODF solder connections allow for secure, permanent installation in commercial refrigeration units and air conditioning split systems. Technicians rely on this refrigeration service valve for its precision seating and the ability to withstand the thermal stresses of field brazing while maintaining a tight, dependable seal for long-term system stability.
Key Benefits:- High Pressure Resilience: Rated for up to 600 PSI, specifically optimized for R410A refrigeration systems.
- Premium Metallurgy: Features a corrosion-resistant stainless steel stem and durable brass housing for longevity in harsh environments.
- Leakproof Seal: Equipped with a high-grade Buna-N gasket to prevent refrigerant loss and maintain vacuum integrity during service.
- Standardized Fit: 3/4" ODF connections ensure compatibility with standard copper tubing in commercial and industrial HVACR setups.
- Broad Temperature Range: Operates effectively from arctic conditions at -40°F up to 250°F for versatile application.
Is the QL171R-12-12 suitable for heat pump applications?
Yes, the Sporlan 278399-121 is designed to handle the pressure and temperature fluctuations typical in both residential and commercial heat pump systems.
Does this valve require disassembly before brazing?
To protect the internal Buna-N seal and internal components from heat damage, it is professional practice to wrap the valve body in a wet rag or use a heat-sink paste during the soldering process.
Is this valve compatible with POE oils?
Yes, the materials used in the QL series service valve are compatible with modern Polyolester (POE) oils and most HCFC and HFC refrigerants.
