Design
& Construction
The full port design has no internal obstruction
to flow and provides a "blind flanges" shut-off when the gate
is closed.
The
valve is a split body, bi-directional, packing less, rubber-lined,
knife-gate valve suitable for a wide range of industrial applications.
The
valve's sealing surface is between two thick, rubber sleeves
which are compressed into the stainless steel or cast iron valve
housing.
The
sleeve is molded with one integral stainless steel stiffener
ring which located the sleeve in the valve housing and helps
the sleeves resist the high shearing forces present when the
gate is driven between them. Split body serve as an external
guide to the valve's knife gate. When in the open position,
the stainless steel gate is completely with-drawn from the process
flow and can be inspected and replaced, if necessary, without
taking the valve out of service.
