The new WS Series sleeves incorporate Linatex® wear resistant technology – which is backed by years of experience in tough abrasive and corrosive environments – and is designed using Weir Minerals’ extensive experience of slurry knife gate valve applications around the world. These factors ensure that the new WS Series sleeves can provide excellent overall valve performance.
In addition, the WS Series valve with its fully interchangeable, one-piece design with integral load distribution rings eliminates the need for multiple pieces and fasteners to make sleeve replacement much easier. Combined with improved sleeve geometry for increased surface contact, friction reduction, and enhanced sealing during valve opening and closing cycles, the new WS Series valve sleeves contribute to an expected low total cost of ownership for customers.
The WS Series wafer-style slurry knife gate valve is designed to provide reliable service in tough abrasive and corrosive slurry applications. In addition to the new valve sleeves, some of the features of the patented WS series valve include: A unibody design and rugged heavy-duty construction, complete bubble-tight bi-directional shut-off with no downstream leakage, wear parts that are easily field replaceable, full port, no seat cavity for solids to accumulate and prevent full gate closure and a universal top plate which can be field adapted to accept any offered actuator.
