Ceramic lined ball valve

Due to advanced ceramic technology, the AKH5 from FLOWSERVE achieves an unequalled performance that offers the ideal solution for many difficult applications in which erosion, wear, abrasion, impact, corrosion and high temperature cause conventional materials to fail. Furthermore the design of the AKH5 offers minimum cavity space that reduces the retention of line media within the body cavity so therefore product contamination problems are significantly reduced.

Wear Resistance: Abrasive slurries have little effect on its rock hard surfaces. Corrosion Resistance: It is virtually inert to acid bases and most other corrosives. Impact Resistance: The composition of the materials and the advanced process technology result in high mechanical strength and toughness. Temperature Resistance: High operating temperatures and thermal shock are not a problem. The melting point of Mg-PSZ ceramic is well beyond the valve limits of 350°C. Higher ratings on request. Cavitation Resistance: Cavitation related problems are sharply reduced due to the extreme hardness of the ceramic material (Rockwell 89).

Unequalled Benefits: The Mg-PSZ ceramics have consistently outperformed steels, cobalt, nickel alloys and other ceramics in a wide range of severe applications such as, steam services, abrasive slurries, fly ash, high temperature corrosives and sand abrasion are only a few of the many conditions where the AKH5 Mg-PSZ lined ball valve has solved serious problems. Also available as V-port ball valve for precise modulating control service.
