RF-SKG Wafer Slurry Knife Gate Valve
Brand: RF Valves, IncThe heavy duty slurry knife gate valve shall be a wafer style, 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.
The roundness of the sleeve shall be maintained by an embedded stiffener ring near the sealing face and a steel disc on the mating face.
Upon closing, the gate will progressively separate the sleeves and once fully closed, will form a bubble tight seal with the upstream sleeve.
The yoke shall consist of two yoke plates 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. Provision must be made for lockouts in the open and closed position with open and closed indicators.
The top bracket must accept manual, pneumatic or electric actuation for easy conversion in the field.
