 Poppet
Dampers
For isolation purposes, poppet dampers are normally fitted to modular duct sections.
A pneumatic cylinder drives the damper disc.
Each isolation poppet damper may be operated remotely from the PLC or locally with a lower actuator. Cylinder mounted limit switches allow PLC indication of damper position. A pin allows mechanical locking of each damper in either the Open or Closed position.
Note: Damper closure only is not sufficient for internal filter access below the tubesheet. For positive isolation, the slip plate must also be installed. At all times entry into these areas must conform to confined space entry regulations.
