KNIFE GATE VALVE
The gure 60R is a wafer at-face anged, bi-directional
knife gate valve. It is suitable for a wide range of industrial
applications, including abrasive slurry services. The full port
design has no internal obstructions and provides a “blind
ange” shut off when closed. The basic simplicity and open
design of the valve invites an extremely wide range of options
and accessories that can be tailored to specic applications.

Design
The valve’s sealing surface is between two thick resilient
sleeves that are compressed into the valve housing. Two
stainless steel stiffener rings are molded into the sleeves to
locate it into the valve housing and to help the sleeves resist
the high shearing forces present when the gate is driven
between them. The body serves as an external guide to the
knife gate blade. When in the open position, the stainless
steel blade is completely withdrawn from the process ow
and can be inspected, and replaced if necessary, without
taking the valve out of service.
