Product Description
The Pneumatic Actuated Knife Gate Valve (BIAV-PAKGV-436) is engineered for handling slurries, viscous fluids, and bulk solids in demanding industrial environments. Its sharp-edged gate cuts through media, ensuring reliable shutoff even in abrasive or clog-prone pipelines. Actuation is automated by pneumatic cylinders, providing rapid and consistent operation.
With stainless steel or ductile iron construction, the BIAV-PAKGV-436 ensures durability against corrosion and wear. Its design minimizes downtime by allowing easy maintenance and seal replacement without removing the valve from the pipeline. The pneumatic actuator provides fast cycle times and can be configured for double-acting or spring-return fail-safe operation.
Suitable for mining, wastewater, pulp and paper, and chemical processing, this valve offers efficiency, precision, and reliability in critical flow systems. All units are factory-tested and supplied with full material traceability documentation.
