Flowserve presents Valtek DiamondBack

Flowserve Corp. announced today the introduction of the Valtek DiamondBack, a control valve with anti-cavitation trim design for severe service applications.
DiamondBack enables control valve users to eliminate high-pressure drop cavitation damage and the associated noise. In addition, the DiamondBack design can be produced in a range of materials, including tungsten carbide, effectively mitigating the effects of erosion. Providing improved reliability and uptime with reduced operating and maintenance costs, DiamondBack also delivers up to 30 percent higher flow than comparable multi-stage valve trim with the same pressure drop. In some applications, this results in a smaller and lighter package than other designs.
DiamondBack cavitation elimination technology is available for installation in all new or existing Valtek Mark Series control valve body sizes.
The new system is able to pass slurries and entrained solids to 15 mm (0.5 in) without plugging. It is available in all commonly specified materials, including 300 and 400 Series stainless steels and high-nickel alloys, as well as exotic alloys and tungsten carbide.
