Frequently Ask Questions
It is a high-performance damper designed to provide extremely tight isolation of air and gas streams. It is particularly useful where preventing gas bypass during shutdown is critical.
Alis Valves manufactures and supplies Zero Leakage Damper Butterfly Valves for power plants, cement plants, steel mills, chemical processing, boilers, industrial ducting, flue gas and process-gas applications.
Zero leakage refers to a valve configuration engineered to achieve extremely tight or effectively zero gas passage in the closed position, according to the specified design and testing requirements.
A standard damper may permit a specified amount of leakage when closed. A zero-leakage damper uses a specialized sealing arrangement to achieve much tighter isolation, making it preferable where gas bypass must be minimized.
