Ferdous Petro Ahan ball valves are designed for high-temperature applications up to 550°C.

The primary innovation of this type of valves resides in the original design for both the seat and ball, which are no longer made by normal steels but by the modified surface coatings such as chromium or tungsten carbides, and others available upon request, designed particularly for appropriate applications at high temperature, high pressure and aggressive environments containing also heavy residuals, abrasive and/or corrosive pieces.

High Performance Butterfly Valves are available in Wafer and Lug type designs conforming to API 609 standard.

The disc construction is Double Offset providing excellent controllability, bubble-tight shut off, greater seat life and smooth operation. Valves are specially designed for applications in chemical, petroleum, hydro carbons processing, pulp & paper and HVAC industries.

Well supported shafts with heavy duty bearings ensure perfect alignment of seat and disc for smooth and trouble-free operation. Valves have been rigorously tested to ensure industry performance requirements.
