Wafer triple eccentric butterfly valve for manual or electric actuator Pn 16

Steel triple eccentric wafer butterfly valves with stainless steel sealing PN 16 in with a manual actuator are devices designed to shut off or regulate flow of the working medium in pipelines. They have a unique design that includes three eccentricities:

1. First eccentricity — offset of the shaft axis relative to the sealing line axis.
2. Second eccentricity — offset of the shaft axis relative to the pipe axis.
3. Third eccentricity — offset of the seat axis relative to the pipe axis.

These design features ensure minimal friction between sealing surfaces when opening and closing the valve, which significantly increases the device's service life and reliability.

Installation features

Wafer valves are mounted between two pipeline flanges without need for additional fasteners or welding. This makes them convenient for installation on existing pipelines without significant changes to the system design.

Advantages of triple eccentric wafer valves

1. Tightness: The stainless steel seal ensures tightness in both directions.
2. Durability: The stainless steel metal seat is resistant to abrasive wear.
3. Low torque: Provides ease of valve control.
4. Minimal friction when opening/closing the disc: This reduces component wear and extends the device's service life.
5. Relatively low weight and short build length

Applications

• Metallurgy;
• Energy;
• Oil refining industry;
• Chemical industry;
• Gas industry;
• Heating and water supply systems.
