The following is a comprehensive information summary about manual knife gate valves, combined with product types, prices, and supplier data:
1、 Product type and characteristics
Structural classification
Open stem/concealed stem type: The open stem design facilitates observation of valve position (such as PZ73H-10C cast steel model), while the concealed stem is suitable for space constrained scenarios.
Sealing material: Ceramic (PZ673TC), rubber (NBR/EPDM) or metal hard seal can be selected. The ceramic valve plate has outstanding wear resistance and is suitable for media such as slurry and slag discharge.
Functional characteristics
Bidirectional sealing design (such as PZ73X-10Q ductile iron valve) can cut off fiber and particle media.
Full bore flow, no groove structure reduces the risk of blockage (such as through type knife gate valve).
