The pneumatic knife gate valve consists of a stainless steel wafer-type knife gate valve and a pneumatic actuator. The bottom of the gate plate features a knife-shaped beveled edge, providing excellent shearing action. This design prevents media blockage during valve closure and enables scraping of adhesions from the sealing surface, automatically clearing debris. It is suitable for controlling the flow of difficult-to-manage fluids such as slurries, powdered materials, and fibers. The PZ673H pneumatic wafer-type knife gate valve typically operates within a pressure range of 1.0 MPa and temperatures below 120°C. Special materials can be used for high-temperature applications. It is widely used in industries such as papermaking, petrochemicals, mining, drainage, and food processing. Multiple seat options are available, and electric or pneumatic actuators can be configured based on on-site control requirements to achieve automated valve operation.
