Description
The function of the RULA damper valve is three fold: modulating air flow, diverting air flow, and isolating equipment from air flow.
These dampers are engineered for isolating air and vent lines where a positive seal is not required.
The shaft stubs are fitted with stuffing glands to seal against a pressure differential where necessary. The shaft stubs are bolted to the robust damper blade.
Actuation can be motorised, pneumatic or hand operated units
