Pneumatic Knife Gate Valve

Pneumatic Knife Gate Valve
A Pneumatic Knife Gate Valve is a specialized valve designed for handling thick fluids, slurry, and abrasive materials in industries where traditional valves may fail due to clogging or excessive wear. Powered by compressed air, the pneumatic actuator operates a sharp-edged blade that cuts through the flow of media and ensures a tight shut-off. This makes it ideal for on-off and isolation applications in systems with viscous or solid-laden fluids. The valve's slim, compact design allows for installation in tight spaces while ensuring minimal pressure drop when fully open.

These valves are typically constructed from durable materials like stainless steel or cast iron to withstand harsh operating conditions, including high pressure and corrosive environments. The knife gate design minimizes fluid entrapment, making it easier to clean and maintain, while the pneumatic actuation allows for quick and efficient operation with minimal manual intervention. Pneumatic Knife Gate Valves are widely used across industries such as wastewater treatment, pulp and paper, chemical processing, and mining.
