Rectangular shut-off dampers for shutting off ducts (gas-tight).
Level of tightness required by KTA Guideline 3601 (German Nuclear Safety Standards Commission, KTA) and by DIN 25414 even when the power supply or compressed air supply fails.
Ready-to-operate unit which consists of the casing, blades and the blade mechanism (over centre locking).
Flanges on both sides, suitable for duct connection.
Suitable for duct pressures up to 5000 Pa.
