What is a Knife Gate Valve?
A gate valve variant with a thin, sharp-edged gate that slices through slurry, pulp, wastewater, or bulk solids. Unidirectional (one-direction shutoff) unless double-disc design. Used in water treatment, pulp & paper, mining, and sewage. Low cost for large DN (DN50–DN1000) applications.
What is a Knife Gate Valve used for?
Knife Gate Valves are used in industrial piping systems for on-off isolation, flow control, or backflow prevention depending on the valve type. They are selected based on the process fluid, operating pressure and temperature, required shutoff class, and pipeline size. Vajra Industrial Solutions supplies Knife Gate Valves certified to API 6D, ASME B16.34, and other applicable standards.
How do I select the right Knife Gate Valve for my application?
Selecting the correct Knife Gate Valve requires specifying: (1) nominal pipe size (NPS/DN), (2) pressure class per ASME B16.34, (3) body and trim material based on fluid compatibility and temperature, (4) end connections (flanged RF/RTJ, butt-weld, socket-weld, or threaded), (5) required certifications (API 6D, ISO 9001, fire-safe API 607).
