Knife Gate Valves

Larox Heavy Duty Knife Gate Valves are built with a cast body and they feature a heavy-duty stainless steel blade. Removable seats on either side of the gate provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry.

Valve Operation

In the open position the two sleeves seal against each other in the  centre of the valve, providing a full bore through which the slurry can travel without being in contact with any metallic components. Closing the valve forces the gate  progressively down between the two mating sleeve ends until it reaches the fully closed position, at which point the sleeves seal tight against either side of the gate, effectively sealing and completely containing the line pressure. Any material/medium discharged between the sleeves during stroking open or closed is collected within the containment area of the valve body and drained via the multiple flushing ports in the body.
