Flanged Triple Offset Butterfly Valve Manufacturer in Africa

Product Introduction

In cases where there is high pressure, heat, and aggressive process operations in industrial pipelines, a very good seal valve is required, hence the importance of having such a valve that will serve the function well. In this case, the Flanged Triple Offset Butterfly Valve is the ideal choice since it has been designed in such a way that it is built for the job by use of the rigid double flanged body and the triple offset sealing. These valves provide bubble-tight shut-off, reduce seat wear, and work efficiently in severe services. They are commonly applied in refineries, petrochemical plants, power stations, offshore platforms, and other industries. African Valve is one of the best Flanged Triple Offset Butterfly Valve Manufacturers in Nigeria, Egypt, South Africa, Kenya, Tanzania, Ghana, and other African countries, that manufactures and supplies this product in different material grades, pressure ratings, end connections and actuations.

What Makes a Flanged Triple Offset Butterfly Valve Different?

While regular butterfly valves use rubber seals in order to create a seal between the valve disc and the seat, the metal seat seal mechanism used by the Flanged Triple Offset Butterfly Valve requires no resiliency in the seat whatsoever. Three offset design allows the valve disc to instantly disengage itself from the seat at the beginning of the operation thus creating a wear-resistant valve without any friction. The flanged design of the valve body creates excellent pipeline rigidity, especially for large pipes that need solid bolted connections and good alignment.

Construction & Operating Principle

The valve works using the 90-degree turn of the disc valve. A camming action is created by three different offsets which ensure that there is no contact between the seals when the valve is working. When the valve is in its full shut condition, the two conical seals meet evenly to guarantee zero leakage operation. The double flange construction helps to distribute the pipe load properly and makes the installation of the valve easier.
