Goggle Dampers are designed as a safety device for gas transport installations to provide a completely thight seal during maintenance. Thy can handle gases with differential pressures up to 200mbar, temperatures up to 200ºC and dust concentrations of up to 1000mg/Nm3.
The Goggle Dampers have specially designed retractable seats. The seats allow axial movement of the damper into the open or closed position thanks to the incorporation of two metallic belows in the valve discs. All damper actuation is hydraulic.
The Goggle Dampers can be bonneted in order to guarantee zero emissions of gas to the atmosphere while the damper is being operated.
The dampers are ATEX certified.
