Knife Gate Valves
Many knife gate valve designs use rubber, urethane or other wear-resistant liners and sleeves to protect the valve body and improve sealing performance. Full-port and flush-bottom designs help reduce pockets where solids can collect, while selected models provide bi-directional sealing and zero discharge to atmosphere.
Knife gate valves are available in a range of configurations for different pressure levels, media and operating conditions, including lined, wafer, flanged and high-pressure slurry designs. Different materials and actuation options can be selected to provide a durable and reliable isolation solution for abrasive, corrosive and solids-laden applications.
Lined Knife Gate Valve
Our Lined Knife Gate Valves are designed for reliable on/off isolation in abrasive and corrosive process applications. The valve body and chest are fully lined with moulded rubber, protecting the metal components from direct contact with the process media.
The flush-bottom, full round port design eliminates cavities where solids can collect and provides zero discharge to atmosphere, making the valve well suited for slurry and other demanding media.
Wafer Knife Gate Valve
Our Wafer Knife Gate Valves provide a compact solution for slurry and abrasive media applications where installation space is limited. The full port design allows the gate to be fully isolated by the sleeves in the open position.
When closed, the gate moves between the sleeves to provide a bi-directional bubble-tight seal with zero downstream leakage. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.
Flanged Knife Gate Valve
Heavy-duty rubber sleeves protect the valve from wear, while the gate passes through the sleeves during closing. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.
High Pressure Slurry Knife Gate Valve
Heavy-duty rubber sleeves provide sealing and wear resistance, while the gate passes through the sleeves during closing. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.
Severe Service Lined Knife Gate Valve
The double-layer sealing system uses an inner seal to isolate the process flow and an outer seal to prevent leakage to atmosphere, providing extended service life and reliable containment in severe-duty applications.
Urethane Lined Knife Gate Valve
The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere.
Severe Service Wafer Sleeve Knife Gate Valve
The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere, improving reliability and service life.
Lined Moulded Knife Gate Valve
Our Lined Moulded Knife Gate Valves are designed for reliable on/off isolation in abrasive and corrosive process applications. The valve body and chest are fully moulded with rubber or urethane lining to protect the valve from wear and chemical attack.
The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere.
