Metal Seated Ball Valve Manufacturer in Africa

Product Introduction

The Metal Seated Ball Valve has been developed to operate in situations where the conditions are harsh in terms of temperature and abrasives where the shut-off performance of soft seated ball valves may deteriorate due to wearing out or failure. The metal seating of the valve makes it very suitable in terms of erosion resistance, high pressures, high temperature and abrasive environments. African Valve is one of the leading Metal Seated Ball Valve Manufacturers in Nigeria, Egypt, South Africa, Kenya, Ghana, and other African countries, that manufactures and supplies this product in different material grades, pressure ratings, end connections and actuations.

Why Is a Metal Seated Ball Valve Used?

The Metal Seated Ball Valve is employed in cases where the operation involves high temperatures, high pressure, corrosive mediums, abrasive slurry, ash handling, catalysts, and situations where normal seats that are made of PTFE or similar material would not perform adequately. The seat and ball are hardened in order to create a metal to metal seal..

Design & Working Principle

The ball valve operates through rotation of the ball 90 degrees from its fully open to its fully closed position. The ball, which is machined precisely from metal, mates with metal seats while being closed for creating a tight fit that can survive extreme conditions prevailing in the process. In order to make sealing surfaces more resistant to erosion, corrosion, and cycles of operation, hard-facing materials such as Stellite, Tungsten Carbide, Chromium Carbide, or others can be used. Fire-safety, anti-static, and blow-out proof stem may be included as extra features.
