Bi-directional KGD Slurry knfie gate vlave with Disc Cover
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.
