🔍 What is a Slurry Knife Gate Valve?

A slurry knife gate valve is a heavy-duty isolation valve with a single or double-acting blade that can cut through slurry and seal off flow. Unlike standard gate valves, they are built to resist erosion, clogging, and build-up of solids.

🔹 Key Features:

  • Full port, unobstructed flow path

  • Available in wafer or lugged design

  • Resilient or metal seats for abrasive materials

  • Options for manual, pneumatic, electric, or hydraulic actuation

  • Designed for high solids, low-pressure systems (typically up to 10 bar)
