Knife gate valves are designed mainly for on-off and isolation services in systems with high content of suspended solids. The knife gate valves are especially beneficial for handling slurry, viscous, corrosive and abrasive media. The valves have a minimised pressure drop in fully open position, they are easy to actuate, they have a relatively low weight and are cost effective.
Knife gate valves designed for use in the pulp and paper industry. Utilizing a sharp, beveled edge, a knife gate was ideally designed to cut through the stringy pulp encountered in the pulp and paper industries. The benefits of knife gates also include that they are easy to actuate and cheap to produce. can be applied wastewater treatment, oil and gas, mining, and power. Knife gate valves became advantageous in sludge and slurry applications because their blades can cut right through thick liquids easily.
