A ductile iron eccentric plug valve controls fluid flow in pipelines by using an offset plug that rotates within the valve body to open or close the flow path. The valve body is made from durable ductile iron, offering excellent wear resistance. The plug is typically made of ductile iron or stainless steel, often coated with resilient materials like rubber or PTFE for improved sealing and corrosion resistance. This type of valve is ideal for throttling applications, providing precise control over flow rates. It is a reliable and versatile choice for various industrial uses, including water and wastewater treatment, chemical processing, and slurry or mining operations.
Designed for Demanding Applications
KFTE Eccentric Plug Valves handle clean/dirty liquids, sludge, slurries, and gases. Suitable for isolation/shutoff or throttling in water/wastewater treatment, power, chemical, mining, and pulp & paper industries.
Exceptional Control Valve
Provides precise throttling with low stiction via permanently lubricated bearings and eccentric action. One-piece cast plug/shaft eliminates backlash and hysteresis. Rigid actuator coupling enhances accuracy.
Wide Body Material Selection
Offers cast iron, acid-resistant bronze, carbon steel, stainless steel, Alloy 20, Monel, and Hastelloy C for applications up to 285 psi (1965 kPa).
Reliable, Multiple Ring Packing
V-Ring packing in machined chamber with adjustable gland ensures self-compensating seal against wear.
Resilient Plug Facings for Long Life
Variety of resilient facings seal tightly even with trapped solids, protecting seat from damage.
Applications of Ductile Iron Eccentric Plug Valve
The ductile iron eccentric plug valve provides reliable and precise flow control in various challenging applications:
Municipal Water & Sewage — Raw water intake, pump isolation, sludge transfer
Wastewater Treatment — Aeration basins, digester recirculation, effluent lines
Mining & Slurry — Tailings, abrasive slurries, dewatering — NBR plug wipes clean every cycle
Chemical Processing — Corrosive fluids with optional Hastelloy trim
Pulp & Paper — Black liquor, green liquor, fibrous stock control
