Pneumatic Shut-Off Sliding Damper
The sliding valve assembly is to be mounted in a fume extraction duct. The valves are to be mounted such that one valve is located in the filter inlet and one is located in the filter outlet duct. The sliding valves are activated by the system control panel. Actuated by pneumatic cylinders, the sliding valves will close automatically to cut off the source of air and to isolate the fire.
When the extraction system is switched off, the valves are closed as well to create a safe situation.
APPLICATIONS:
Sliding valves are part of Lincoln Electric’s GUARDIAN™ fire safety solutions for fume control systems and is recommended for applications with an increased fire risk, such as:
- Robotic welding of oily stamped products
- Robotic and automatic welding of oily products
- Manual welding of oily products
- Cutting tables
- Schools/Other areas with risk of cigarette butts
