Gas-tight shut-off dampers are designed to ensure the 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.

  • Compact design and robust actuator mechanism allow for any installation orientation
  • Maximum air leakage rate is 0.0028 (l/s)/m² or 0.01 (m³/h)/m² at a differential pressure of 2000 Pa
  • Gas-tight closure, even when there is no power, due to special over centre locking mechanism
  • Variants with hand wheel, pneumatic actuator or electric actuator
  • Brass or stainless steel bearings
  • Powder-coated casing and blades
  • Maximum pressure loading of 5000 Pa, in closing direction
  • Available in standard sizes and many intermediate sizes


Optional equipment and accessories

  • Flange holes
  • Limit switches
  • Double acting pneumatic actuator, with optional solenoid valve
  • Electric actuator 3 × 230 V AC (400 V AC) or 230 V AC
