The goggle damper valve is a specially designed knifegate valve to isolate a pipe area and allow the passage of persons without air sealing, in environments with high dust concentration. Once he knife gate is closed, it is pushed by hydraulic jacks to press it against the seal and thus ensure tightness. The CMO Valves goggle damper valves are designed for speeds under 30 m/s and temperatures of up to 200 ºC. When the goggle is fully open the conduit is completely free, so there are no pressure drops. It cannot be used for regulation purposes.
The CMO Valves goggle damper is designed for pneumatic transport of air or gases at different temperatures. They are particularly suitable for controlling the flow of gas in pipelines.
Used mainly in:
• Cogeneration plants.
• Thermal power stations.
• Electrical power stations.
• Chemical plants.
• Energy sector.
From DN500 to DN2500
* Other DNs on request.
