The resilient-seated eccentric plug valve features an eccentric (offset) plug that rotates to control the flow path. "Resilient-seated" refers to the use of a soft, flexible material (like rubber or elastomer) for the seating surface, providing a tight seal when the valve is closed. The plug’s offset design reduces friction and wear during operation, allowing for a tight shutoff with minimal torque. This enhances the valve's longevity and reliability. The resilient seat can absorb minor debris and imperfections, maintaining a reliable seal. Eccentric plug valves offer excellent throttling capabilities for precise fluid flow control.
Designed for Demanding Applications
KFTE Resilient-Seated Eccentric Plug Valves are built to handle a wide range of media, including clean and dirty liquids, sludge, slurries, and gases. These valves are ideal for both isolation/shutoff and throttling/control services and are commonly used in water treatment, wastewater treatment, power generation, chemicals, mining, and pulp & paper industries.
Exceptional Control and Accuracy
These valves provide precise throttling control. The permanently lubricated bearings and eccentric design minimize stiction, allowing for smooth, incremental adjustments. The one-piece cast plug and shaft eliminate backlash and hysteresis, and the firm actuator coupling ensures high accuracy.
Versatile Material Options
KFTE offers a full range of body materials for various applications, rated 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 design provides excellent sealing performance and self-compensates for wear over time.
Resilient Plug Facings for Long Service Life
KFTE Resilient-Seated Eccentric Plug Valves are equipped with resilient plug facings that provide a tight seal, even when small solids are present between the plug and seat. This feature helps protect the seat from damage and ensures a longer service life.
Applications of Resilient-Seated Eccentric Plug Valve
Resilient-seated eccentric plug valves are highly versatile and are used in several demanding industrial applications:
Water and Wastewater Treatment: These valves provide precise control over the flow of water, ensuring reliable shutoff or throttling in treatment processes.
Chemical Processing: Their corrosion-resistant and durable construction makes them ideal for handling chemicals in a wide range of processing environments.
Slurry and Mining Operations: The resilient seat design allows them to handle abrasive fluids and slurries with minimal wear, extending valve life and reducing maintenance costs.
