Heavy duty slurry knife gate valves has been specifically designed as a space-saving option for heavy duty applications.
The long-lasting replaceable elastomer sleeves offer a reliable sealing solution.
The full port design allows the gate to be fully isolated by the sleeves from the process in the open position. As the gate closes, it pushes between the two sleeves, discharging a small amount of material out of the bottom of the valve. This serves to prevent material build up in the seat area to ensure a full gate closure, as well as to prevent damage to the gate. When the
gate is in the open or closed position, there is a 100% bi-directional bubble tight seal and zero downstream leakage.
DA pneumatic valves are supplied with dust boots (bellows) as standard to protect valve stems and actuators.
All manual and electro-mechanical valves are also supplied with stem covers as standard for additional stem and actuator protection.
All valves are fully lined ensuring no metal comes in contact with slurry flow.
All valves are supplied with A2-70 hardware (nuts, bolts, and washers) for corrosion protection.
Each component is individually epoxy painted prior to assembly.
Guanli Heavy duty knife gate valves feature
*Manual or automated actuators available
*Two-coat epoxy paint
*Dust boots supplied as standard to protect stem and actuators
*Full port, bi-directional design
*Metric or imperial flange patterns
*Open body prevents gate damage during actuation
*Manual lockout option available
*Long-wearing, field replaceable sleeves, create sealing surface
SSwitch position description:*Open position:
*Gate positioned above seals
*Metal parts not in contact with slurry
*Unobstructed port area sliminates turbulence, Minimizes pressure drop across valve
*No seat cavity where solids can collect and prevent full gate closure
Closed Position:*Gate travels completely through sleeves to provide blind flange sut off and expel solids.
*100% Isolation-bubble tight shut-off results in absolutely zero downstream leakage.
* Double-seated design provides bidirectional flow and shut-off
