Ultra-low leak butterfly damper
This is a butterfly damper developed with a focus on the maintenance safety of large-diameter ducts, designed to minimize leakage to the utmost limit.
By using it in combination with a closure plate, it completely blocks the outflow of gas in the duct and ensures safety during maintenance.
basic information
■Main Material: FRP We will select and propose corrosion-resistant and heat-resistant resins according to the environment in which they will be used, so please inform us of the gas composition when making inquiries. ■Connection Diameter: Φ500 to Φ1,800 (standard size) We have many achievements in other sizes as well, so please contact us. ■Leak Rate (Gas): Less than 0.1% (with gas static pressure ±5KPa) We can accommodate some non-standard conditions, so please inform us of your usage conditions when making inquiries.
Price information
The specifications of the damper vary depending on the composition of the target gas and the airflow, so we will provide a separate estimate for the price.
Delivery Time
Applications/Examples of results
By installing shut-off plates and the main damper on the upstream and downstream sides of the equipment branched from the common duct, we have eliminated gas inflow, allowing for safe maintenance of the equipment interior without stopping operations.
