Pneumatic Knife Gate Valve

A pneumatic knife gate valve is a high-performance industrial shut-off valve equipped with a pneumatic actuator.It uses compressed air as the power source to drive the gate plate to open and close quickly and stably.

Designed with a sharp-edged gate,it can effectively shear fibers,solid particles,sludge,pulp and high-viscosity media.It perfectly prevents pipeline blockage and achieves reliable tight shut-off for harsh solid-liquid mixed working conditions.The full-bore straight-through flow passage brings minimal flow resistance,no material deposition and smooth medium transportation.

This valve features a compact short structure,light weight and easy installation.It can realize automatic control,remote operation and rapid on-off action,which greatly improves production efficiency and reduces manual operation.Multiple sealing options including soft seal and hard seal are available to adapt to low temperature,high temperature,abrasion and corrosive environments.Wafer,flanged and lug connection types can meet various pipeline installation requirements.

With simple structure,sensitive response,stable performance and low maintenance cost,the pneumatic knife gate valve is widely used in sewage treatment,environmental protection,mining,metallurgy,papermaking,chemical industry,electric power and building materials industries.It is an ideal automatic control valve for slurry,tailings,coal ash,waste residue and complex abrasive media.
