Superior 586wa-8st Wa Series Welded Ball Valve 1/2 Inch

Product Description

The SUPERIOR 586wa-8st is a full port, welded ball valve from the WA Series, designed for use in refrigeration systems where a secure, leak-resistant connection is required. Welded-end construction eliminates threaded or flare fittings at the valve body, making it well suited for installations where vibration, pressure cycling, or refrigerant containment are primary concerns. With a 1/2 inch full port bore, the valve delivers unrestricted flow through the line when open. Refrigeration technicians and HVAC mechanics install this type of valve during system assembly, line set work, and component isolation tasks.

The 586wa-8st is intended for refrigeration piping applications where a permanent, weld-in shutoff or isolation valve is needed. Full port design minimizes pressure drop across the valve, which is important in systems where refrigerant flow efficiency directly affects system performance. This valve is appropriate for commercial and residential refrigeration line sets, refrigerant distribution manifolds, and similar closed-loop refrigerant piping systems. Installation requires welding capability appropriate to the refrigerant piping material and system working pressure.

Key Features

• Full port bore for unrestricted refrigerant flow and minimal pressure drop
• Welded-end body construction for a permanent, leak-resistant connection
• WA Series design suited for refrigeration piping environments
• 1/2 inch line size accommodates standard residential and light commercial refrigerant tubing

Compatibility

Designed as an OEM-style welded ball valve for 1/2 inch refrigeration piping systems where WA Series welded valves are specified.

Installation Notes

Installation of this valve requires a certified refrigeration or HVAC technician with appropriate brazing or welding qualifications for refrigerant piping work. Recover and evacuate all refrigerant from the system before cutting into any refrigerant line. Follow applicable mechanical codes and refrigerant handling regulations during installation. Allow all weld joints to cool and pressure-test the completed assembly before recharging the system.
