Feature

This type of knife gate valve is a unidirectional knife gate valve with bonnet. The completely enclosed body-bonnet structure ensures 0 leakage from the knife gate to surrounding. This valve is very suitable to contaminated/hazardous media for the safety of surrounding.





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.
