Superior Refrigeration 591WA-11ST Ball Valve

The Superior Refrigeration 591WA-11ST Ball Valve is a technician-grade 1-1/8 inch ODF refrigeration shutoff valve designed for high-pressure fluid control in commercial HVACR systems. Built with a forged brass body and robotically welded joints, this full port ball valve ensures unrestricted flow and 100% factory-tested leak-free performance. It features a non-directional flow design, allowing for versatile installation in any orientation, which is essential for tight mechanical rooms or complex rack systems. The Integra-Seal WA series utilizes a dual Teflon (PTFE) stem seal and a unique seal cap design that allows for valve operation without removing the cap, providing a secondary seal to prevent refrigerant loss. Engineered to handle a maximum working pressure of 800 PSIG and a service temperature range of -40°F to +325°F, this 1-1/8 ODS ball valve is compatible with CO2, CFC, HFC, and HCFC refrigerants, making it a reliable solution for liquid, suction, or hot gas line applications.

• Full Flow Design: Minimizes pressure drop and maximizes system efficiency with a 1.00" port diameter.
• Robotic Weld Technology: Provides a continuous body joint that eliminates potential leak paths common in threaded or multi-piece valves.
• Enhanced Stem Sealing: Employs a primary internal packing nut and a secondary Teflon gasket within the seal cap for redundant leak protection.
• Positive Stop Operation: Includes mechanical internal stops to provide clear tactile feedback for 1/4-turn open and closed positions.
• Refrigerant Versatility: Suitable for use with modern refrigerants including high-pressure R-410A and CO2 systems within rated limits.

• Can this valve be installed in either direction? Yes, the 591WA-11ST is a non-directional valve, meaning flow can move in either direction without compromising performance or shutoff integrity.
• Does the seal cap need to be removed to operate the valve? No. A major benefit of the Superior Integra-Seal design is that it permits operation through the cap, reducing the risk of losing the cap or damaging the secondary seal during service.
• Is this valve rated for high-pressure R-410A systems? Yes, with a maximum working pressure of 800 PSIG, it comfortably exceeds the requirements for R-410A liquid and suction lines.
