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:
Series L 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.
