Special Construction Designs
For openings up to DN 1000 mm. Specially flat in construction, robust stainless steel construction with stainless steel extension as required. Can be dowelled in front of or behind wall openings, both sides sealed. Simple installation, very durable, operationally reliable.
Material: stainless steel, bearings from Cu/Zn alloy, selected resistant ring seal.
DN 200 to DN 1000 mm
Allows water to flow in one direction. Easily opened and secure in closing due to flexible bearings. Can be dowelled; if required, with DIN.flange.
Material: stainless steel, bearings from Cu/Zn alloy, proven cover sealing.
DN 150 mm to DN 250 mm
For flooding of tanks by high groundwater level as safeguard against floating. With standard wall crests for force-locking and waterproof installation in concrete floor.
Material: stainless steel with emovable lid and replaceable seal
10.00 m WS (1 bar).
0.05 WS (5 mbar)
Float-controlled outlet gate
DN 100 to DN 400 mm
Opens, throttles and closes in- and outflows. Limits the underwater level to a given maximum height e.g. in a pump sump. Can be dowelled.
