Types of Aira’s Knife Edge Gate Valves
We offer three specialized variants of knife edge gate valves, engineered for optimal performance in challenging industrial environments.
- Bi Directional Knife Edge Gate Valve
Available in sizes from 50mm to 300mm, this valve handles pressures from 5 to 10 bar and temperatures up to 200°C. Manufactured as per MSS SP-81 standards, it features body materials like CI, SGI, DI, and WCB, with disc options in SS 304/316/316L/310 or Duplex 2205. The seat materials (NBR/EPDM/Viton/PTFE) ensure tight sealing (Class VI leakage) for applications in mining, pulp & paper, cement, sugar, and fossil fuel power plants.
- Uni Directional Knife Edge Gate Valve
With a broader size range (50mm to 1200mm) and higher temperature resistance (up to 250°C), this valve operates from 0.5 to 10 bar pressure. Compliant with MSS SP-81 standards, it offers multiple body styles (single piece, semi lug, full lug, wafer) and materials (CI, WCB, CF8, CF8M, SS 316). Ideal for slurry handling, sugar processing, and material handling industries, it provides Class VI sealing with optional metal-to-metal seats for tougher applications.
- Self Sealing Knife Edge Gate Valve
This valve uses two rubber seats on the clip to create a sealing effect. This self sealing knife edge gate valves are available in 50MM to 800MM size range, supports Bi-directional flow. This valve can be upstand with upto 80°C temperature and hold up to 16 Bar working pressure.
How Aira’s Knife Edge Gate Valve Works?
The knife edge design features a sharp-edged disc that cuts through thick fluids, slurries, and viscous media, preventing clogging and ensuring smooth operation. When actuated, the blade creates a tight seal against the seat, minimizing leakage.
Key benefits include:
- Superior flow control for abrasive and high-solid-content media
- Minimal pressure drop due to full-bore design
- Durable construction resistant to wear and corrosion
- Easy maintenance with simple, robust components
