The is the definitive guideline for rubber-seated butterfly valves used in municipal water and wastewater systems . Established by the American Water Works Association (AWWA) , this standard ensures that valves are durable, reliable, and capable of tight shutoff in critical infrastructure.
If you’re an engineer, contractor, or utility employee: While many users search for a , it
| Feature | Specification | |---------|---------------| | | Rubber-Seated Butterfly Valves | | Scope | 3-in. (75 mm) through 144-in. (3,600 mm) | | Pressure Classes | 25, 50, 100, 150, 250, 300 psi | | Key Sections | Materials, design, testing, marking |
One of the most critical features of the (titled Rubber-Seated Butterfly Valves ) is its precise definition of the temperature and pressure ratings for different valve classes, which is essential for engineers specifying equipment for water and wastewater facilities.
