Design
NEOPERL® flow regulators are designed to be directly inserted into an application device to save the space and cost of an additional fitting.

Flow regulators consist of a dynamic elastomer, an engineered circular seating area (core) and a body (housing) in selected models. The gap between the core and the elastomer is the open passage for the water flow. The core openings can be on the inside of the elastomer or on the outside of the elastomer.
Flow Regulating Check Valves (CV-FR series)
Flow regulators can be combined with a check valve to provide backflow protection and flow control (pressure compensating). These unique compact cylindrical cartridges are compatible with the mating cavity of DW check valves of the same size.
Flow Regulating Aerators (PCA® line)
Combined with a NEOPERL® aerator flow regulators help produce a precisely controlled aerated or laminar stream or a spray to meet Code and Standard requirements and save water and energy.
