  • Suitable for square or rectangular opening cross-sections
  • Centrally or laterally arranged actuator connection

Construction features

  • Welded stainless steel construction
  • Flap body in modular system
  • Performed in accordance with the design requirements
  • Sidewalls adapted to the opening sequence
  • Seal over entire swivel operation, no lateral flow around

Materials

  • Threshold with side bolsters 1.4301 / 1.4571

Tightness

Tilting flap weirs are applicable for prevention of level regulation. The design related leakage is always less than listed to DIN 19569-4 class 1.

Actuator

Tilting flap weirs can be combined with many actuators. An automatic movement will be realized by an electric actuator or by pneumatic/hydraulic drive.
