Speciality Valve is one of the best Slurry Knife Gate Valve Manufacturers in India, and we provide heavy-duty valves designed to operate under the harshest flow conditions. The operation of thick, abrasive, or viscous media, such as slurry, demands a specific valve solution. 

Slurry Knife Gate Valve: 

Slurry knife gate valve is made particularly for on/off and isolation duties in systems carrying slurry, a suspension of solid particles within liquid. It has a sharp-edged gate cutting through dense and heavy media without clogging. 

Why Required? 

Standard valves tend to fail or wear rapidly in slurry service due to abrasive wear and deposition of sediment. Knife gate valves provide an unobstructed flow passage and a shear-type cutting action, providing steady flow and low maintenance. 

Key Components of Slurry Knife Gate Valve: 

• Body (cast steel or fabricated steel) 
• Knife-shaped gate 
• Seat rings (metal or resilient) 
• Stem and actuator (electric, pneumatic, or manual) 
• Bonnet (optional, design dependent) 

Working of Slurry Knife Gate Valve: 

Upon actuation, the gate descends into the flow path to shut off or isolate the slurry. With its thin, pointed configuration, the valve can cut through the slurry without clogging. When being withdrawn, the valve offers a full-bore passage for unobstructed flow, having a low pressure drop. 

Advantages of Slurry Knife Gate Valve: 

• Excellent performance in abrasive and high-solid-content media 
• Low-pressure drop when open 
• Minimal maintenance needed 
• Can be made with replaceable seats and gate options 
• May be automated for remote control 

Functions of Slurry Knife Gate Valve: 

• Slurry flow control 
• On/off isolation in mining and process industries 
• Avoids sediment deposition and valve clogging
