Emerson Alco 806758 Ball Valve

The Emerson Alco 806758 (Model BVS078) is a heavy-duty, manual shut-off refrigeration ball valve designed for professional isolation of suction, discharge, and liquid lines. Engineered with a 7/8" ODF sweat connection, this valve features a full port design to minimize pressure drop and ensure maximum flow capacity across the system. It is constructed with a forged brass body and 100% copper extended tubes, making it a reliable choice for high-pressure applications with a 650 PSI max pressure rating. This bi-directional valve is compatible with modern HCFC and HFC refrigerants, including R410A and R744 (CO2), handling fluid temperatures from -40°F to 250°F. The integrated access valve allows for convenient pressure monitoring and charging, while the hermetic welded design ensures a leak-free seal. For contractors, the low-friction operating stem and secure cap strap provide a durable, field-ready solution for maintaining mission-critical HVACR pipework during system shutdowns.

• Optimized Flow: The full port ball valve construction eliminates significant pressure drops, maintaining system efficiency in 7/8 inch ODF lines.
• Versatile Compatibility: Rated for 650 PSI, specifically designed for R410A refrigeration systems and other high-pressure HFC/HCFC applications.
• Durable Construction: Forged brass body with a hermetic welded design protects against leaks and environmental corrosion.
• Secondary Access: Features an integrated access port with a tethered cap for simplified diagnostic checks and refrigerant recovery.
• Bi-Directional Flow: Allows for installation in any orientation without compromising performance or shut-off integrity.

Is the BVS078 compatible with R-410A systems?
Yes, the Emerson BVS078 is fully compatible with R-410A. It handles a working pressure up to 650 PSIG, meeting the requirements for most high-pressure refrigerant applications.

Does this valve include a service port?
Yes, this model includes an integrated access valve, which allows technicians to connect gauges or charging hoses directly at the isolation point without installing additional tees.

Can this ball valve be installed in either direction?
The 806758 ball valve features bi-directional flow characteristics, meaning it will provide a positive seal and full flow regardless of which side is designated as the inlet or outlet.
