The new SKW valve—Slurry Knife Wafer—was developed for use in the oil and gas, mining, minerals and metallurgy, power and waste water industries, where abrasive or corrosive slurries, powders or coarse substances are processed. The main benefit to a full-bore design is that the SKW valve itself becomes an integral part of the pipe and allows it to process the same fluids in the harshest of conditions. In addition to its strength and resistance to aggressive slurries, the valve is designed as a full port fluid control device that allows a more efficient process, requiring less pumping energy to operate.
The SKW valve incorporates smart manufacturing techniques and incorporates a cast single-piece body, which eliminates any potential leak paths from the body and offers a versatile tower construction that will accept manual, electric, hydraulic or pneumatic forms of actuation. The valve offers proprietary and innovative sleeves with load distribution rings incorporated within, along with a robust valve structure.
An added benefit is that when in the “open position,” the SKW valve’s rubber ring sleeves are the only parts in contact with the medium as a way to reduce any potential corrosion or deterioration due to wear-and-tear, even when processing the most abrasive slurries. The most significant feature are load distribution rings imbedded into the rubber ring sleeves–a feature that has been incorporated into the SKW valve design and completely eliminates the inherent problems of competitors’ products, where tight piping tolerances have caused the compression and destruction of the rubber sleeves.
