AKH5 Ceramic Lined Valve

The AKH5 Ceramic Lined Valve achieves an unequalled performance that offers the ideal solution for many difficult applications in which erosion, wear, abrasion, impact, corrosion and high-temperature fluctuations cause conventional materials to fail. The AKH5 Ceramic Lined Valve is recommended when nothing else will work in abrasive slurries, high-temperature corrosives and services with large temperature fluctuations. Available in 25 mm (1 in), 40 mm (11⁄2 in), 50 mm (2 in), 80 mm (3 in) and 100 mm (4 in) sizes.

In addition, 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.

All interior body surfaces and the ball are made of solid Mg-PSZ for superior erosion/corrosion resistance. Excellent strength and thermal shock resistance. A wide selection of stem material options available 316 stainless steel, Hastelloy C-276 or Mg-PSZ (Partially Stabilized Zirconia) ceramic. Full port minimizes pressure loss and increases flow capacity to reduce energy and pumping costs.

The Mg-PSZ Zirconia Ceramic material offers:

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,

Features
