The Emerson Alco 806752 (BVS038) is a professional-grade 3/8" ODF refrigeration ball valve designed for the safe isolation of suction, discharge, and liquid lines. Engineered with a forged brass body and extended 100% copper connections, this hermetically welded ball valve ensures leak-free performance under high operational stress. It features a full port design to achieve minimal pressure drop across the system, maintaining optimal flow velocity in critical HVACR cycles. This bi-directional valve is optimized for compatibility with R-410A, HFC, and HCFC refrigerants, as well as sub-critical CO2 (R-744) applications. The integrated Schrader access port allows technicians to perform pressure testing or refrigerant recovery without breaking the primary seal. Its low friction chrome-plated brass ball and virgin PTFE seats provide a smooth quarter-turn action and superior seat sealing across a wide fluid temperature range of -40°F to 250°F. Key Benefits: Full Flow Characteristics: Internally ported to align with pipe diameter, effectively eliminating turbulence and significant pressure drop. Hermetic Construction: The welded refrigeration valve design removes the risk of external leaks commonly associated with flared or gasketed components. High-Pressure Rated: Certified for a maximum working pressure of 650 PSIG (45 bar), making it suitable for modern high-pressure systems. Operational Reliability: Features a blowout-proof stem and a cap retained by a durable strap to prevent job site loss during maintenance. Common Questions: Is the Emerson 806752 compatible with POE lubricants? Yes, the brass refrigeration valve materials and PTFE seals are fully compatible with Mineral, Synthetic, and Polyol-Ester (POE) oils. Can this be mounted in any orientation? Yes, the bi-directional flow design allows for flexible installation in both vertical and horizontal refrigerant piping configurations. Does it require disassembly before brazing? No, while standard heat-sink precautions (wet rags) should be used, the hermetic design does not allow for internal disassembly.
