Series L - Bidirectional Knife Gate Valve

Liquids low in solids, Bi-directional Flow, <145 PSI Pressure

DESCRIPTION

Two-piece cast body, joined by screws, with internal guides for smooth movement of gate during operation.

Provides high flow rates with low pressure drop. Various seat and packing materials available.

Face-to-face dimension in accordance with CMO Valves standard.

GENERAL APPLICATIONS

This knife gate valve is suitable for liquids that contain a maximum of 20% suspended solids. It is also recommended in gravity discharge applications for solids and fine particles, because of its half-moon shape which cuts the flow and high consistency fluids.

Designed for a wide range of applications such as:

  • Paper Industry
  • Mining
  • Chemical Plants
  • Food Industry
  • Pumping
  • Silo Emptying
  • Sewage Treatment
