The pneumatic knife gate valve is a type of valve designed for handling fluids containing solids, slurries, or viscous media. It is widely used in industries where precise flow control and reliable shut-off are required. The valve is actuated by a pneumatic system, allowing for automated operation and integration into control systems.

Design Features:
-
Knife Gate Design: The valve features a sharp-edged gate that cuts through thick fluids, slurries, or solids, ensuring smooth operation and minimal clogging.
-
Pneumatic Actuator: The valve is equipped with a pneumatic actuator, which uses compressed air to open and close the gate. This allows for quick and precise control.
-
Sealing Mechanism: The valve uses elastomeric seals or resilient seats to ensure a tight shut-off, even in harsh conditions.
-
Compact Design: The knife gate valve has a slim, lightweight design, making it suitable for applications with limited space.
-
Bi-Directional Flow: Many models are designed to handle flow in both directions, providing flexibility in installation.
