Swirl valve CEV 425 OP. 20l/s. Tube 200mm. Head 1.5m. Stainless steel 316L

Fixed swirl valve type OP is equipped with an emergency overflow ø110 and mounting plate 395x344mm. To be mounted on a flat wall. (Round pit is possible, pit diameter must be specified). Pit mooring at least 850x850mm internally. The swirl valves limit the flow in the pipe system, using the pressure head on the supply side. Medium rainwater, for disconnecting RWA from DW systems in newly improved separated sewer systems and discharge from other sediment systems. Favorable drainage characteristic with high self-cleaning in the pipe system. Stainless steel AISI 316L (1.4404). For type CE/V with a so-called 'drowned' inlet, there must be a height difference of 0.40 meters between the outgoing pipe and the bottom of the pit. The valve is mounted in front of the discharge pipe by means of a plate. The supply and discharge pipes may be at the same height. If the supply pipe is a storage pipe, we recommend this pipe to be approximately 5 to 10 cm. higher than the drain pipe, due to the self-cleaning effect. Stainless steel mounting anchors M10 are included. The CEV OP type is supplied without a pipe for emergency overflow. The height of the emergency overflow is determined by the customer
