Manual/pneumatic actuator stainless steel through conduit knife
gate valve, lug type/wafer type
Descripe
Knife gate valve is a kind of gate valve which is shut off valve
directly.Its gate head is designed with bevel cutting edge,which
has a cutting action to medium.Knife gate valves are suitable for
those mediums contained fibers and solid particles,and sewage
treatment systems.Operated by manual,pneumatic or electric
actuatores,knife gate valves are widely used in the process of
automatic control systems in paper making , mining , chemical and
sewage treatment industries.

Design Feature
Body
· Cast-in guide claws at the port bottom for gate fixture, instead
of a groove, eliminates.
· potential valve shutoff clogging while providing tight seal.
These guide claws push gate.
· towards seat for tight seal in closed position.
· Integral body design ensures easy assembly and 0 shell leakage.
· Full port design minimizes pressure drop and maximizes flow
capacity.
· Completely enclosed structure ensures 0 leakage from valve to the
surrounding, which is perfect for contaminated/hazardous media for
the safety of surrounding.
· Super thin body design and compact construction contribute to
easy installation.
GATE
· Beveled knife edge provides strong cutting stress and tight
sealing.
· Gate thickness can be increased to meet higher pressure.
Seat
· Side-entry seat is replaceable, reducing the cost of maintenance.
· L-shape seat retainer locks seat into valve body and covers seat
side to prevent direct.
· flow flushing.
Stem
· Stem cover is available to ensure long service life for stem.
· Two thrust bearings minimize torque for operation.
· Grease nipple is available to ease bearing lubrication.
