Knife Edge Gate Valve Bidhan Nagar

Precision Valve for Tight Shut-Off

Leveraging on our vast industrial experience, we are a supplier of a large assortment of products and machinery. Knife-edge gate valves are manufactured for applications requiring full-bore flow and tight sealing. The knife-edge design cuts through solids and thick fluids, making these valves ideal for harsh conditions.

1 Core Advantages

1 Enables unobstructed flow with minimal pressure drop. 2 Sharp edge disc slices through sludge and debris. 3. Provides bubble-tight shut-off in demanding pipelines

Widely preferred in challenging process environments.

2 Design Variations

1 Rising stem and non-rising stem types 2 Manual, electric, or pneumatic actuation 3 Stainless steel and alloy steel construction

Various options to match industrial needs.

3 Industry Applications

1 Slurry handling in mining and mineral processing 2 Pulp and paper industry for thick fluids 3 Wastewater treatment requiring solids control

Used largely in heavy industrial and chemical sectors.

4 Benefits to Users

1 Resists clogging and jamming caused by solids. 2 Offers durability under abrasive and corrosive conditions. 3 Simplifies maintenance with fewer moving parts

Engineered for longevity in tough service conditions.

5 Material & Build Details

1 Body – Cast steel, stainless steel, or alloy steel 2 Disc – Hardened stainless steel or alloy with knife edge 3 Seat – Metal or resilient, depending on fluid compatibility

Manufactured for strength and leak-proof performance.

6 Installation Tips

1. Align the valve properly with the pipe flange to avoid seat damage. 2. Use proper gaskets and bolts with the recommended torque. 3. Verify the actuator function before commissioning

Correct installation ensures valve reliability.

7 Maintenance Practices

1. Regular inspection for erosion on the knife edge. 2. Lubricate stem threads to prevent corrosion. 3. Replace seats if leakage is detected

Maintenance extends service life and performance.
