Pneumatic knife gate valve
A pneumatic knife gate valve moves a linear knife gate using compressed-air actuation. The title identifies body form and drive energy only; it does not guarantee bidirectional sealing, mounting direction, air pressure, or slurry suitability. Selection must use actual breakaway and running force, solids behaviour, gate path, actuator clearance, and operating cycle.
Application and duty
Automated isolation with a knife-gate body after fluid conditions and actuator force are verified
