Gate Valves
McWane Plant & Industrial offers a full line of AWWA-compliant gate valves engineered for durability, performance, and long service life in waterworks and industrial applications. Our portfolio includes rotating double disc gate valves (AWWA C500) with self-cleaning seating surfaces, resilient seated gate valves (C509 full wall and C515 reduced wall), and solid wedge gate valves (AWWA C500). Designed for smooth operation and minimal maintenance, MPI gate valves are available in a wide range of sizes, end connections, and both NRS and OS&Y configurations to meet the demands of municipal and infrastructure projects.
Rotating Double Disc Gate Valves
Our Rotating Double Disc Gate Valves feature an innovative rotating seating surface, which self-cleans and seats in a different location with each operation. Through the moving seating surface action, the sealing components wear more evenly – remaining consistent, smooth and properly fitting. This dramatically extends the life of the valve, and minimizes the chance of fouling, leakage or failure.
Resilient Seated Gate Valves
Enhance your pipeline efficiency with our resilient seated gate valve—designed for compact installations without compromising performance. Engineered with a ductile iron body and a fully encapsulated EPDM rubber seat, this valve ensures tight sealing, corrosion resistance, and smooth operation in water and wastewater systems. Compliant with AWWA C515 or AWWA C509 standards, this valve delivers reliable shutoff and long service life for municipal, industrial, and utility applications.
Solid Wedge Gate Valve
MPI's Solid Wedge Gate Valves feature a single solid wedge that offers strong mechanical sealing through compression. Available in a range of sizes and configurations, these valves are designed, manufactured and tested in accordance with AWWA C500. The simple design and rugged construction provide years of reliable service.
