The AWWA C517 eccentric plug valve are designed to control the flow of water and other fluids in municipal and industrial applications. The valve moves off-center, reducing wear and providing a tight seal. Its offset eccentric plug rotates away from the seat during opening, minimizing friction, reducing operating torque, and extending service life. Constructed primarily from durable and resilient materials, it ensures longevity and reliability and prevents leakage. Available with flanged, mechanical joint, or grooved ends, these valves have various end connections.
Designed for Demanding Applications
KFTE Eccentric Plug Valves are designed to handle a wide range of media, including clean and dirty liquids, sludge, slurries, and gases. They are suitable for both isolation and throttling/control services, commonly used in industries such as water treatment, wastewater treatment, power generation, chemicals, mining, and pulp & paper.
Exceptional Control and Accuracy
These valves offer excellent throttling control with precise adjustment. Permanently lubricated bearings and the eccentric design minimize stiction, allowing for smooth, incremental steps. The one-piece cast plug and shaft eliminate backlash and hysteresis, while a firm actuator coupling ensures high control accuracy.
Versatile Body Materials
KFTE provides a comprehensive range of body materials to meet diverse application needs, with a pressure rating up to 285 psi (1965 kPa). Available materials include cast iron, acid-resistant bronze, carbon steel, stainless steel, Alloy 20, Monel, and Hastelloy C.
Reliable, Multiple Ring Packing
The valve features multiple V-ring packing within a machined chamber and an adjustable gland. This advanced packing design compensates for wear, ensuring a reliable, long-lasting seal.
Resilient Plug Facings for Extended Service Life
KFTE Eccentric Plug Valves come with resilient plug facings that maintain a tight seal, even when small solids are present between the plug and seat. This design protects the seat from damage and extends the valve's service life.
Applications of AWWA C517 Eccentric Plug Valve
The AWWA C517 eccentric plug valve excels in municipal and industrial systems requiring AWWA compliance:
Potable Water Distribution — Zero-leakage isolation for pump stations, reservoirs, and transmission lines.
Wastewater & Sewage — Handles raw sewage, grit, and rags without clogging; resilient seat wipes clean each cycle.
