Bray 401000-21804595 Series 40 High-Performance Butterfly Valve Rebuild Kit 10-Inch

The Bray 401000-21804595 is an OEM rebuild kit designed specifically for the 10-inch Bray McCannalok Series 40 high-performance butterfly valve. This genuine Bray replacement kit contains the essential sealing and wear components needed to restore full valve performance during scheduled maintenance or unplanned repairs.

The Bray Series 40 is an ASME Class 150 double-offset, high-performance butterfly valve engineered for demanding industrial service. The rebuild kit provides the components necessary to bring worn or degraded valves back to factory operating condition, extending service life and deferring costly full valve replacement.

Kit Includes:

• Seat seal and stem seal components for the 10-inch valve body
• Gaskets and sealing elements to restore zero-leakage shutoff performance
• Replacement wear parts compatible with the Series 40/41 ASME Class 150 valve design

Series 40 Valve Compatibility Highlights:

• Valve Series: Bray McCannalok Series 40 (ASME Class 150)
• Valve Size: 10-inch (10#)
• Design Standard: ASME B16.34, API 609 Category B, MSS SP-68
• Seat Tightness: API 598 / MSS SP-61
• Temperature Range (Resilient Seated): -62°F to 500°F (-52°C to 260°C)
• Pressure Rating: ASME Class 150

Bray's double-offset cam-action disc design pulls the disc cleanly away from the seat during opening, minimizing seat wear and operating torque. Replacing seals and internal components with genuine Bray rebuild kit parts ensures proper dimensional fit and continued compliance with original design specifications. Suitable for applications including chilled water, caustic, steam, and other industrial media consistent with the Series 40 resilient-seated design.
