This knife gate valve has a rugged, durable construction and a uni-body design to ensure long life and reliability. The two-piece rubber sleeve system is flexible and pressure assisted. The sleeves are easy to replace and do not require the valve to be disassembled. They are available in a variety of materials. The way the system is designed allows the valve to cycle in heavy slurries efficiently.

The upper seal design is new, replaceable and has no packing. Thanks to its design, there is no need for periodic adjustment. The system is also self-lubricating. Sizes 2-16" are available. The full port construction of the valves reduces turbulence and pressure drop. Large highly concentrated solids are purged from the open bottom. Additional features include an enclosed bronze bushing, protected grease chamber and bi-directional shutoff.
