Double-plate penstock with rectangular opening, 3-sided sealing
Opening dimensions 300 × 300 mm to 4500 × 4500 mm
Pressure level possible on the front or back
Pressure level corresponds to the plate height (both plates closed)
Regular operation by lowering the upper plate in front of the lower plate

Other materials available on request.
Leak tightness class
- Leak rate better than DIN EN 19569, Part 4, Table 1:
- Pressure on front side max. 1% of 0.05 to 0.1l · s-1 · m-1 (leak tightness class 3)
- Pressure on back side max. 0.05 of 0.1 l · s-1 · m-1 (leak tightness class 3)
Application options
- One actuation:
- Upper plate lowerable, lower plate fixed
- Both plates can be lifted, full stroke
- Two actuation:
- Each plate driven separately
- Upper and lower plate independently mobile
Mounting
- Fastening lateral:
- Concreted into recess
- Anchoring to the wall in front of the opening
- Anchoring laterally on the wall
- Fastening in the bottom:
- Concreted into recess
