Superior Refrigeration 587WA-12ST Ball Valve

The Superior Refrigeration 587WA-12ST ball valve is a full-port, bi-directional 3/4" ODF refrigerant isolation valve engineered for critical applications in commercial HVACR systems. Built with a robust forged brass body and a chrome-plated ball, this valve ensures unrestricted flow with minimum pressure drop across the line. Designed for compatibility with common refrigerants including R-410A, R-134a, and R-404A, it features PTFE seats and a rupture-proof polished brass stem for leak-free performance under high-pressure conditions. The sweat connection design simplifies brazing into liquid, suction, or discharge lines. Contractors value the 1/4 turn actuation and the integrated Schrader access port, which allows for convenient charging or pressure monitoring without additional line taps. This straight-through ball valve provides a reliable seal in temperatures ranging from -40°F to 300°F, making it a standard for high-performance HVAC refrigeration components.

Key Benefits for Technicians:

• Full Port Design: Maximizes capacity and reduces turbulence, ensuring peak system efficiency.
• Extended Copper Ends: Allows for easy installation and brazing without disassembly, protecting the internal seals.
• Hermetic Seal: Features double O-ring stem seals to prevent refrigerant leaks and moisture ingress.
• Full Working Pressure: Rated up to 700 PSI, making it suitable for modern high-pressure refrigerants like R-410A.
• Access Valve: Includes a built-in 1/4" flare access port for rapid diagnostic testing and service.

Commonly Asked Questions:

Can this valve be mounted in any orientation?
Yes, the 587WA-12ST is a bi-directional valve and can be installed in any orientation within the piping layout, provided there is sufficient clearance for the 1/4 turn handle.

Is this valve compatible with POE and PVE oils?
Yes, the materials of construction, including the PTFE seats and neoprene O-rings, are compatible with all standard HVAC oils and refrigerants.

Does the valve require a wet rag during brazing?
While the extended ends are designed to dissipate heat, standard best practices for refrigeration brazing recommend using a heat-sink or wet rag on the valve body to protect the internal seals from excessive thermal transfer.
