ESEP AISI 316 vortex flow control, series UCY, is a flow limiter. It is designed to limit the flow in overflow basins, surge basins and sewer systems (combined and rainwater) to a predefined, maximum drainage capacity. The ESEP vortex flow control consists of a durable, stainless steel (AISI 316) casing with no moving parts. At low flow rates, the vortex flow control allows the (waste) water to flow through unhindered.

Available in several types depending on the situation
