Damper isolation valves

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
