Knife Gate Valves
Achieve reliable shutoff, longer service life and lower total cost of ownership in utility service to severe slurry.
Achieve reliable shutoff, longer service life and lower total cost of ownership in utility service to severe slurry.
We manufacture knife gate valves for light to heavy slurry service in the mining and mineral processing, power, pulp and paper, waste water and chemical industries. In critical slurry applications where absolute zero downstream leakage is essential, these high performance knife gate valves can be relied on to deliver a 100% bubble-tight isolation shut off every time. Offering a cost effective isolation and control solution, these products provide high performance and increased sensitivity to the environment to help reduce customer risk and maximize production.
Conventional Knife Gate Valves
Reliable, low maintenance knife gate valves for plant utility services.
Slurry Knife Gate Valves
Knife gate valves with proven elastomer sleeves for durable, tight shutoff in slurry service.
Severe Service Knife Gate Valves
Knife gate valves engineered to excel in the most challenging heavy slurry applications.
Precision engineered seats delivering 100% insolation, time and time again
Upgrade your severe service knife gate valves to extend valve life and service intervals, and lower your total cost of ownership.
Designed for a range of on/off low to medium density slurry applications such as coal preparation plants, SU10R knife gate valve offers isolation with a field replaceable snap-in liner which protects the area from abrasion and corrosive slurries.
Constructed wafer-style with Mark III sleeve and zero leakage, Clarkson KGD valves are well suited for slurry service. A more robust support disc is incorporated into the one-piece design which resists over compression of the sleeve.
Isolation Valve FAQs
A knife gate valve is a valve that uses a knife edge to cut through solids content that could prevent the valve from sealing completely.
Knife gate valves are used for light to heavy slurry service in the mining and mineral processing, power, pulp and paper, waste water and chemical industries.
A knife gate valve comes with a sharp gate that moves up and down by a screw mechanism, a seat through which the gate moves, and packing material to prevent leaks.
