Fixed vortex valve type OP is equipped with a ø110 emergency overflow and a 292x292mm mounting plate. Can be mounted on a flat wall. (Round manholes are possible; the manhole diameter must be specified.) Manhole dimensions: minimum 450x450mm internal. The vortex valves limit the flow in the piping system, utilizing pressure head on the inlet side. Medium rainwater, for disconnecting RWA (rainwater discharge) from DWA (water discharge) systems in newly improved separated sewer systems and discharge from other sedimentation systems. Favorable discharge characteristics with high self-cleaning in the piping system. Stainless steel AISI 316L (1.4404). For type CE/V with a so-called "flooded" inlet, there must be a 0.40 meter height difference between the outgoing pipe and the manhole bottom. The valve is mounted in front of the discharge pipe using a plate. The inlet and discharge pipes may be at the same height. If the supply pipe is a storage pipe, we recommend installing it approximately 5 to 10 cm higher than the discharge pipe to facilitate self-cleaning. M10 stainless steel mounting anchors are included. The CEV OP model is supplied without an emergency overflow pipe. The height of the emergency overflow is determined by the customer.
