Stainless steel penstocks for shut-off and control in wastewater applications — two designs for different requirements. The EROX®plus features a patented sliding wedge system for technically demanding applications requiring maximum leak-tightness. The ERI®plus offers a compact design with separate sliding and sealing system for universal plant construction. Both are wall-mounted with square openings and suitable for use in wastewater systems, stormwater retention basins, flood protection and power plants.
