The AP-Series 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 the surrounding. This valve is very suitable to contaminated/hazardous media for the safety of surrounding.
Body:
- Completely enclosed structure ensures 0 leakage from valve to the surrounding, perfect for contaminated/hazardous media for the safety of surrounding.
- Super thin body design and compact construction contribute easy installation.
Gate:
- Knife edge gate provides strong cutting stress and tight sealing.
- Gate is hard chromium coated after delicate surface grinding, providing abrasion resistance and corrosion resistance against the flow flushing.
Seat:
- Side entry seat is replaceable, reducing the maintenance cost.
- Preloaded seat is adjustable to meet different sealing class and compensates normal seat wear.
- Seat retainer covers the side of seat and prevents seat from direct flow flushing.
