ANSI Class Knife Gate

Valves (KHP)

Design Features:

DeZURIK ANSI Class Knife Gate Valves withstand high pressures and abrasive slurries found in mining (including oil sands processing), steel, power, chemical, and paper industries. Ideal for isolation in high-pressure, high-density slurry lines, the valves are pressure rated to ANSI Class 150 and 300.

Available in sizes from 6 - 36 inches (150 – 900mm), these High Performance Knife Gate Valves feature cast carbon steel construction to meet demanding performance requirements. Valves feature purge-ports to allow flushing of media from the valve interior. ANSI Class 150 valves match standard pipe IDs, and ANSI Class 300 valves match extra-strong pipe IDs. The seat/wear ring matches the pipeline ID to reduce turbulence and pressure loss across the valve. A wide variety of hardened trim options is available on the gate, seat and the wear ring.

An integral bonnet is standard on ANSI Class 300 valves. To reduce maintenance costs, a pressure-energized rod seal and heavy-duty braided scraper ring are replaceable without removing the bonnet or rod.
