**90° Swing Bronze Ball Valve: Quarter-Turn Bronze Ball Valves**
These quarter-turn bronze ball valves are manufactured in accordance with the American Association of Valve and Fitting Manufacturer Standardization Association (MSS-SP-110) standard. They are rated for non-impact cold water applications at 600 psi operating pressure. The valve body should feature a welded connection, with a three-piece design that allows for easy disassembly during brazing installation. Each valve is equipped with PTFE seats to ensure a tight seal, and the internal flow path remains full bore, without any reduction in diameter. Additionally, they include a blowout-proof stem and a chrome brass or bronze ball for enhanced durability.
Newly purchased valves must be cleaned and packaged by the manufacturer for use in oxygen tubing systems. These valves comply with MSS-SP-110 and are rated for 600 psi non-shock cold working pressure. The body should have soldered ends and a three-piece design that facilitates disassembly for brazing. The valves should feature TFE seats and offer a full-port design for optimal flow.
**Available Valves:**
- **US NIBCO S-595-YX** (welded)
- **NIBCO S595-YX** (solder)
- **US NIBCO CS-595-YX-EC** (welded, with extended valve cover)
- **US NIBCO CS-595-66-EC** (with extended bonnet and stainless steel trim)
**Acceptable Valves with 6" Stub Ends:**
- **NIBCO CS595-66-YX-EC** (solder with expanded cup and stainless steel trim)
**Note:** If the piping is insulated, the selected ball valve must be fitted with a 2-inch longer, non-thermally conductive handle to prevent heat transfer. A protective sleeve should also be provided to allow safe operation of the valve without breaking the vapor seal or disturbing the insulation.
**Alternative Valves:**
- **US NIBCO S-595-YXNS** (welded)
- **NIBCO S595-YXNS** (solder)
This ensures proper functionality, safety, and compliance in both standard and insulated piping environments.
