Compared with conventional butterfly or ball valves, the knife gate structure is better suited to applications where powder columns, granular materials or product build-up may interfere with normal valve movement. Sanitary Pneumatic Knife Gate Valve is stainless-steel sanitary construction makes it suitable for pharmaceutical, food, battery material and chemical processing systems.
The pneumatic actuator allows the valve to be controlled directly from a PLC or process-control system. This is useful for automated conveying lines, hopper discharge systems and batch processing equipment where operators need reliable opening and closing without manual intervention.
When opening, the gate retracts from the flow path to provide a large unobstructed passage. During closing, the sharp gate moves through the material before reaching the sealing position, helping isolate the downstream process quickly.
The stainless-steel gate can penetrate compacted powders, granules and accumulated material, reducing the possibility of bridging or blockage at the valve.
Once fully open, the gate is largely removed from the product stream. This reduces flow resistance and helps minimize material retention during discharge.
The sealing assembly helps limit powder leakage and dust emissions after the gate reaches the closed position, supporting cleaner and safer processing environments.
AVM uses SS316L stainless steel for product-contact components, providing corrosion resistance and a suitable surface for hygienic processing.
The internal structure is designed to minimize product retention and simplify cleaning. FDA-compliant sealing options can be selected for applicable pharmaceutical and food applications.
Suitable for API, excipient, tablet and capsule production lines where controlled material isolation and contamination prevention are required.
Used for cathode, anode and other dry powder transfer systems where automated isolation and dust control are important.
Suitable for flour, starch, sugar, milk powder and other bulk ingredients.
Used for powders, granules and other dry materials in hoppers, silos, reactors and conveying systems.
Can be installed at transfer points to isolate equipment during maintenance, cleaning or batch changeover.

The AVM Sanitary Pneumatic Knife Gate Valve provides fast pneumatic opening and closing, while its sharp knife gate effectively cuts through accumulated powders and bulk materials to reduce blockage. The reliable sealing structure helps minimize dust leakage and product loss, while the full-port design provides efficient material flow when fully open.
Manufactured with SS316L sanitary construction, the valve is suitable for hygienic processing and can be integrated with automated process-control systems. Its practical structure also simplifies installation and maintenance, making it suitable for pharmaceutical, food, chemical, battery and other powder and bulk-solid handling applications.
A pharmaceutical manufacturer needed an automatically controlled isolation valve between a powder hopper and downstream conveying equipment. The previous valve configuration was prone to material accumulation around the closing area.
AVM supplied a Sanitary Pneumatic Knife Gate Valve with sanitary stainless-steel construction. The customer reported that the knife gate moved through accumulated powder more reliably, while pneumatic control allowed the valve to be linked with the existing conveying sequence. The customer particularly valued the combination of fast isolation, easier process control and reduced material blockage.
A battery-material producer required an isolation valve beneath a powder hopper where dust containment and automatic operation were important. The AVM valve was integrated into the discharge system with pneumatic control.
According to the customer's operating feedback, the valve provided stable repeated opening and closing and effective isolation during equipment shutdown and material-transfer cycles, helping reduce manual intervention around the powder discharge point.
AVM sanitary valve solutions can be supplied with FDA-compliant sealing materials and hygienic configurations designed to support GMP production requirements. Depending on the project, material certificates and applicable CE and ISO 9001 quality documentation can also be provided.
The knife-shaped gate can cut through powders and accumulated material while pneumatic actuation provides fast and repeatable automatic isolation.
