SS Through Conduit Knife Gate Valve For Sewage Treatment Industry

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.
