Flow Regulators
NEOPERL® flow regulators consist of an o-ring, an engineered circular seating area (core) and a body (housing) in selected models. The gap between the core and the o-ring is the open passage for the water flow. The core openings can be on the inside of the o-ring or on the outside of the o-ring.

NEOPERL® flow regulators are designed to be directly inserted into an application device to save the space and cost of an additional fitting. Selected models help meet the 8 lb pull-out force requirement for shower applications (press-fit design).
 
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.

Three cartridge sizes are available (12, 14 and 15mm) covering a range of flow rates from 0.5 gpm to 4 gpm.
 
Flow Regulating Aerators 
(PCA® line)

Combined with a NEOPERL® faucet attachment 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. The PCA lines of faucet attachments are available in 0.5 gpm, 1.0 gpm, 1.5 gpm and 2.2 gpm in Regular, Junior and in the new Tom Thumb size.
