Flowrox launches new industrial valve for processing abrasive and corrosive substances

Flowrox, a specialist in heavy-duty industrial valve manufacturing and services, is launching a new slurry knife gate product designed to enhance current pipeline equipment and processes using enhanced technology for fluid control.

The Slurry Knife Wafer (SKW) valve was developed for use in the oil and gas, mining, minerals and metallurgy, power and wastewater industries, where abrasive or corrosive slurries, powders or coarse substances are processed.

Flowrox has engineered the valve at full-bore with no flow restrictions, allowing processes with abrasive or corrosive fluids—such as lime slurry or mineral slurries—to move without compromising performance. The main benefit to a full-bore design is that the SKW valve itself becomes a part of the pipe and allows it to process the same fluids in the harshest of conditions.

In addition to its 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 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.

When in the 'open position', the valve's heavy-duty rubber ring sleeves are the only parts in contact with the medium in order to reduce any potential corrosion or deterioration due to wear-and-tear, even when processing the most abrasive slurries. Load distribution rings are embedded into the rubber ring sleeves to prevent their compression and destruction.
