Emerson Alco 806756 Ball Valve

The Emerson Alco 806756 (Model BVS058) is a professional-grade 5/8" ODF sweat refrigeration ball valve engineered for critical isolation in high-pressure HVACR systems. Built with a robust forged brass body and 100% copper extended tubes, this manual shut-off valve is designed to withstand a 650 PSI maximum working pressure. It features a full-port, bi-directional flow design that minimizes pressure drop while ensuring reliable performance across suction, discharge, and liquid lines. The integrated Schrader access valve allows technicians to perform pressure monitoring or charging without breaking the primary circuit. Strategically designed for low operating friction, the valve employs a hermetic welded construction to prevent refrigerant leaks, making it fully compatible with modern HFC and HCFC refrigerants, including R-410A. The stem cap is securely retained by a rugged strap, preventing component loss during field maintenance and ensuring a tight seal for long-term system integrity.

• Enhanced System Isolation: Facilitates rapid sectioning of pipework for maintenance, reducing refrigerant recovery time.
• Maximum Pressure Durability: Rated for up to 650 PSIG, providing a high safety margin for R-410A and CO2 (subcritical) applications.
• Integrated Service Access: The built-in access port simplifies diagnostics and pressure checks during routine service calls.
• Full Flow Efficiency: The large internal bore ensures minimal turbulence and protects system efficiency in refrigeration manual shut off scenarios.
• Versatile Compatibility: Designed for seamless integration with varied ODF solder connections in commercial refrigeration and air conditioning units.

Is the BVS058 compatible with R-410A systems?
Yes, this valve is specifically rated for high-pressure HFC refrigerants and has a maximum working pressure of 650 PSI, making it ideal for R-410A suction and liquid lines.

Can this valve be mounted in any orientation?
The Emerson BVS series is bi-directional and can be installed in any position, provided there is sufficient clearance to remove the valve stem cap for operation.

Does the access valve require a separate core?
The unit comes equipped with a standard Schrader core and a locking seal cap, though technicians should ensure the core is removed during the brazing process to prevent heat damage to the internal seals.
