FAQ
What is a pneumatic knife gate valve, and how does it work?
A pneumatic knife gate valve functions as a specific valve which controls fluid flow through a sharp-edged gate that cuts through media. The valve operates with a pneumatic actuator to achieve automated precise control of opening and closing functions for efficient flow regulation. The actuator operates through compressed air to move the gate which slides vertically between blocking and allowing flow.
What industries typically use pneumatic knife gate valves?
Pneumatic knife gate valves serve industries that need strong flow control solutions including:
– Mining and mineral processing
– Wastewater treatment
- Pulp and paper
- Chemical and petrochemical processing
– Food and beverage manufacturing
What types of media can a pneumatic knife gate valve handle?
– Abrasive slurries
– High-viscosity fluids
– Corrosive chemicals
– Gaseous substances
– Clean or dirty water
What materials are used in pneumatic knife gate valves?
The body and disc components use durable materials including WCB, CF8, CF8M, stainless steel (SS304, SS316, SS316L) and 2520. The seats are available in STL, EPDM, PTFE, and VITON to handle a broad range of applications.
