Series F - Unidirectional Knife Gate Valve

Solids, Uni-directional Flow, Low Pressure

DESCRIPTION

  • One-piece cast body with guides to support gate and seat wedges.
  • Provides high flow rates with low pressure drops.
  • Various seat and packing materials available.
  • Face-to-face dimension in accordance with CMO Valves standard.
  • It has an arrow on the body indicating the flow direction.

GENERAL APPLICATIONS

This knife gate valve is suitable for working with dry products like powder and grain. It is generally used for gravity discharge of dry solids.

Designed for applications such as:

  • Mining
  • Silo Emptying
  • Electrical Power Stations
  • Chemical Plants
  • Food Industry

Series F valves are available with handwheel rising and non-rising stem, pneumatic, hydraulic, handwheel gear box, and electric drives.

Typically temperatures up to 565° C (1,050° F) pose no issue. If you have a higher temperature application, call or email us so we can learn more about your application.
