Big Knife™ valves were developed to bridge the gap between your typical knife-gate
valve, which is often viewed as a throwaway valve and the more expensive high performance
Stargate O-Port valve. When knife-gate valves are used in applications with solids
in the flow media, these valves tend to press the solids into the seat area preventing
the valve from closing. The Big Knife™ valve is designed for applications with a
low percentage of solids.

Applications that have a higher percentage of solids,
frequent duty cycles and/or where Class VI shut-off is required should use the Stargate
O-Port™ valves.

Big Knife™ valve are designed to allow solids to accumulate in the bottom of the
valve, to a certain extent, as the valve is being closed. The bottom of the valve
can be flushed out in order to prevent compaction of material in that area. |

|
The amount of accumulated solids depends on valve size, particle size and percentage
of solids in the flow. The valve can also be flushed out and cleaned whilst on line. |
