Product Overview
A DN300 pneumatic knife gate valve is a specialized valve designed for controlling the flow of various media, including liquids with suspended solids, slurries, and powders. The “DN300” designation indicates a nominal diameter of 300 millimeters (approximately 12 inches), making it suitable for large-scale industrial applications.
Pneumatic Knife Gate Valve with knife-type damper has good shearing action, making it most suitable for pulp, powder materials, and fibers that are difficult to control in fluid flow. It is widely used in industries such as papermaking, petrochemicals, mining, drainage, and food. The valve offers multiple seat options and can be equipped with electric or pneumatic actuators to meet field control requirements, enabling automation of valve operations.
• The ultra-short length structure saves material and greatly reduces the overall weight of the pipeline system.
• It occupies little effective space, effectively supports pipeline strength, and reduces the possibility of pipeline vibration.
• PTFE packing ensures flexible, reliable sealing and smooth operation.
• The knife gate function effectively controls various types of medium flow.
• The hard seal stainless steel material with disc spray welding processing extends the valve’s capability to meet temperature and pressure requirements.
