Superior Refrigeration 594WA-25ST Ball Valve

The Superior Refrigeration 594WA-25ST Ball Valve is a professional-grade 2-5/8" ODF refrigerant shutoff valve engineered for high-capacity commercial HVACR systems. Built with a robust forged brass body and copper tube extensions, this reduced port ball valve provides reliable isolation for liquid, suction, and hot gas lines. It features a unique dual stem seal design using PTFE packing, eliminating the need for synthetic O-rings and ensuring a leak-free performance even under extreme refrigerant system conditions. The quarter-turn actuation allows for rapid shutoff, while the Integra-Seal cap enables valve operation without cap removal—a critical feature for efficiency during system maintenance. Compatible with all major fluorinated refrigerants including R-410A, R-22, and CO2 (R-744), this valve is rated for a 700 PSI working pressure and a temperature range of -40°F to +325°F. Its bi-directional flow capability and non-directional installation design make it a versatile solution for complex rack systems and condensing units.

• Reduced Port Design: Optimized for precise flow control with a CV rating of 250.
• Hermetic Seal Integrity: 100% factory-tested welded refrigeration ball valve joints prevent external leaks.
• PTFE Ball Seals: Secondary seal activation provides redundancy if the primary seal is compromised.
• Internal Forged Stops: Mechanical stops ensure positive open and closed positions for secure operation.
• Refrigerant Compatibility: Suitable for use with CFC, HCFC, HFC, HFO, and CO2 refrigerants.

Is this valve suitable for high-pressure CO2 applications?
Yes, the 594WA-25ST is rated for a design working pressure of 700 PSIG and is compatible with R-744 (CO2) subcritical systems within that pressure range.

Does this model include an access port for charging?
No, the 594WA series is the manual shutoff version without an access fitting. For an integrated Schrader valve, the WAS series is required.

Can I install this valve in any orientation?
Yes, these are non-directional flow valves and can be mounted horizontally or vertically to fit your piping layout.
