Gate Valves

Full-bore isolation valves for water, wastewater, and slurry applications. Resilient seated gate valves and lever-operated knife gate valves.

About Gate Valves

We stock gate valves and knife gate valves for a wide range of applications. Gate valves provide full-bore shutoff for water distribution, while knife gate valves are designed for slurry, solids, and wastewater where a shearing action is needed.

Applications

Water distributionWastewater treatmentMining and slurryProcess isolation

Key Features

Gate Valves vs Knife Gate Valves

Gate Valves (Wedge)

Traditional gate valves use a wedge-shaped disc that lowers into the flow path. Best for clean water service where a tight seal is required.

  • • Resilient seated for bubble-tight shutoff
  • • Non-rising stem for underground install
  • • Ductile iron or stainless steel body
  • • Water distribution, fire protection

Knife Gate Valves

Knife gate valves use a thin blade that slices through the media. Designed for slurry, solids, pulp, and wastewater where a shearing action is needed.

  • • Cuts through solids and fibrous media
  • • Lever operated for quick manual control
  • • 316 stainless steel construction
  • • Metal or EPDM resilient seated

Choosing the Right Valve

Use a Gate Valve when:

  • • Clean water or liquid service
  • • Underground or buried installations
  • • Bubble-tight shutoff required
  • • Water mains, fire systems, irrigation

Use a Knife Gate Valve when:

  • • Slurry, solids, or fibrous media
  • • Wastewater or sewage
  • • Frequent manual operation needed
  • • Mining, pulp & paper, food processing
