Pneumatic cast steel knife gate valve with flange connection, resistant to high temperature and pressure

When the knife gate valve is closed, the sealing surface can be sealed solely by the medium pressure, that is, the medium pressure presses the sealing surface of the gate against the seat on the other side to ensure sealing—this is self-sealing. Most gate valves use forced sealing, meaning that when the valve is closed, external force is required to forcibly press the gate against the seat to ensure the tightness of the sealing surface. This type of valve is generally installed vertically in pipelines.

Driving methods for knife gate valves: manual, chain wheel, electric, pneumatic, hydraulic, bevel gear, electro-hydraulic, and pneumatic-hydraulic driving methods, etc.
External structures of knife gate valves: rising stem and non-rising stem types.
Materials of knife gate valves: cast iron, cast steel, carbon steel, stainless steel, fluorine-lined, etc.
Sealing types of knife gate valves: hard sealing, soft sealing, single-sided sealing, double-sided sealing, and other sealing materials.
