A Tight Shut Off Damper is a high-performance industrial damper specifically designed to completely isolate or block airflow or gas flow when in the closed position. It ensures zero or near-zero leakage, making it ideal for critical applications where airtight sealing is essential—such as in toxic gas handling, hazardous environments, high-temperature processes, or energy-saving HVAC systems.

Key Features

• Zero Leakage Design: Engineered for bubble-tight sealing, often compliant with international standards like AMCA, API, or ISO. Perfect for systems demanding absolute shut-off.
• Robust Construction: Usually built from carbon steel, stainless steel, or alloy steel, with high-grade gaskets and seals made of silicone, Viton, PTFE, or metal-to-metal contact for harsh conditions.
• Precision Sealing Mechanism: Utilizes knife-edge blades, seal air systems, inflatable seals, or spring-loaded blade edges to maintain full shut-off integrity.
• Actuation Options: Can be operated manually, or automated using electric, pneumatic, or hydraulic actuators for precise control and fast response.
• Temperature & Pressure Resistance: Designed to withstand high temperatures, pressure variations, and corrosive environments depending on the application's requirements.
