AWWA C517 eccentric plug valves are designed to control the flow of water and other fluids in municipal and industrial applications.The valve features an eccentric plug that moves off-center, reducing wear and providing a tight seal. This design helps in minimizing the torque required to operate the valve.Typically constructed from durable materials such as ductile iron, stainless steel, or other corrosion-resistant alloys to ensure longevity and reliability.The valve seat is usually resilient, often made from materials like rubber or other elastomers, to ensure a tight seal and prevent leakage.These valves can have various end connections, including flanged, mechanical joint, or grooved ends, to suit different piping systems.
Designed for Demanding Applications
KFTE Eccentric Plug Valves are used to handle clean and dirty liquids, sludge, slurries and gases. They can be used for either isolation/shutoff or throttling/control services. Eccentric plug valves are used in water treatment, wastewater treatment, power, chemical, mining and pulp & paper
An Exceptional Control Valve
KFTE Eccentric Plug Valve provides excellent throttling control and accuracy. Permanently lubricated bearings and eccentric action reduces stiction, allowing for small incremental and controllable steps. The one-piece casts plug and shaft effectively eliminates mechanical backlash and hysteresis. In addition, the firm coupling connecting the valve to the actuator increases measurable accuracy.
Wide Selection of Body Materials
KFTE offers the most complete line of eccentric body materials to meet the requirements of a broad range of applications up to 285 psi (1965 kPa). Materials available include cast iron, acid-resistant bronze, carbon steel, stainless steel, Alloy 20, Monel and Hastelloy C.
Reliable, Multiple Ring Packing
Multiple V-Ring packing in a machined packing chamber and an adjustable gland provide the best technology in packing design. The multiple packing rings are compressed to provide self-compensation for wear.
Resilient Plug Facings for Long Service Life
KFTE Eccentric Plug valves are available with a variety of resilient plug facings. Even if small solids are trapped between the plug and seat, the resilient faced plug seals tightly, preventing seat damage.
