AWWA C515 & AWWA C509 Resilient Wedge Gate Valves
Engineered for Reliable Isolation in Water & Wastewater Systems
Gate valves are a proven and trusted solution for isolation in water and wastewater systems, providing a full, unobstructed flow path and dependable shut-off when it matters most. Their simple yet rugged design makes them well-suited for high-pressure transmission mains, surge-prone systems, and buried service applications where long-term reliability is critical.
Common Gate Valve Applications Include
- Irrigation Networks
- Potable Water Distribution
- Waterworks Connections
- Fire Protection Systems
- Wastewater and Sewage Systems
- Industrial Process Systems
