The Shipham Valves Catalog design of these valves enables frictionless sealing and provides a tight shut off even in high-temperature systems. This type of piping system is often used in metallurgy, electric power and oil production applications. Triple offset butterfly valves feature a metal-to-metal seal, unlike the elastomeric or soft material seals of conventional rotary butterfly valves. They are more tolerable to dirt and will function in contaminated systems as well.
This type of valve uses an angular disc seat that is inclined around the axis of the shaft and piping line centerline or sealing point to reduce running torque and friction between the seat and body. This also helps to minimize the squeezing complications that can occur in concentric butterfly valves.
These types of valves are rated class 150, meaning they can function in clean or dirty fluids. However, the sealing mechanism is less tolerable to wear and tear so the valves will need to be replaced at a much more frequent rate than other rotary butterfly valves.
