Offset Disk Dampers

FORENSERVTEK Offset Disk Dampers (Also known as 3-lever Valves) are the optimal choice for applications where butterfly dampers cannot achieve full tight shut-off, as the shaft penetration point of butterfly dampers always creates a sealing discontinuity and becomes a potential leakage source.
They are also ideal when an air sealing system is not available on-site and installation space is insufficient for guillotine dampers, especially for media containing relatively few viscous impurities.
Under high-temperature and variable-temperature conditions, the expansion and contraction deformation of the valve body and disc of FORENSERVTEK Offset Disk Dampers will not affect the sealing performance, eliminating the risk of jamming.
The sealing surface forms a continuous 360° inner perimeter, providing a full contact surface when the blade is closed, thus enabling zero leakage.
This makes them an ideal solution for industrial equipment isolation.
