Emerson Clarkson KS1 knife gate valve

Wednesday, 28 April, 2021 | Supplied by: Emerson Automation Solutions


Emerson has announced the Clarkson KS1 knife gate valve, designed to help mine, oil sands, and pulp and paper operators achieve increased availability for challenging slurry processes.

The knife gate valve features a gate edge seal design that creates a continuous seal around the gate, together with a precision-moulded elastomer seat. The heavy-duty seat is said to increase the contact area and resilient sealing ability of the valve compared to standard O-ring designs, resulting in improved isolation performance over an extended life cycle.

The valve design has been optimised for heavy slurry conditions with a full round port that eliminates protrusions into the flow, which minimises turbulence across the valve and reduces wear on valve components and downstream equipment. Reversible, rotatable wear rings on both sides of the valve protect the seat and extend maintenance intervals.

The valve is repairable with standard tools and readily available spare parts. Adjustments can be made to the packing system that dynamically self-adjust pressure to the gate edge seal system. The product is designed to standard MSS SP-135 face-to-face dimensions for simple change-out and upgrade of underperforming installed valves.

The product comes in sizes from 2″ through to 30″ with a variety of available flange patterns; an ASME Class 150 pressure rating of 290 psi at ambient temperature; and a temperature rating up to 150°C. Alternate materials are available to combat extraordinary abrasive and corrosive process conditions and a variety of automation options can be configured to suit.
