The heavy duty slurry knife gate valve shall be a flanged, bi-directional valve with a packingless design. The full port bore shall be formed by two heavy duty elastomer sleeves, one on either side of the gate. Each sleeve shall have an integrally moulded encapsulated stiffener ring to maintain the shape of the sleeve. Upon closing, the gate will progressively seperate the sleeves and once fully closed, willwill form a bubble tight seal with the upstream sleeves. The yoke shall consist of two cover plates and four heavy duty angular supports, that fully enclose the gate, spindle and clevis to protect these components from slurry splatter. The yoke design will allow for easy mounting of proximity or limit switches. Steel proximity switch covers must be provided to prevent damage during transport and operation.operation. The top bracket must accept pneumatic, electric or hydraulic actuation for easy conversion in the field. The valve shall have lifting lugs close to the centre of gravity of the valve with open supports at the top of the yoke for ease of manuevering during installation and storage.

Topworks
When the valve is fully opened the two identical elastomer sleeves push against each other to form a cavity free , bubble tight seal to contain the line pressure.
When the gate moves from the open to closed position, the gate seperates the facing sleeves until it completely closes and seals the bore from both directions.
As the gate strokes, the gate tip creates a gap between the facing sleeves allowing media that could potentially clog orjam the valve to be purged to atmosphere.

The INSAMCOR SKG LB valve utilizes an integrally moulded encapsulated stiffener ring to maintain the rounded shape of the sleeves under heavy shearing forces.
