Sterilight Flow Restrictors

We are pleased to offer a full selection of Sterilight inline flow restrictors ranging from 0.5 gallons per minute to 20.0 gallons per minute. They are designed specifically to ensure that the maximum flow ratings of ultraviolet (UV) sterilizers are not exceeded, thereby ensuring that an adequate UV dose is always maintained. We recommend that you select a restrictor that has a GPM restriction rating equal to or less than the maximum flow rate of your UV sterilizer based on a UV dose of 40,000 µWs/cm2.

We offer 2 basic types of flow restrictors, 316L stainless steel and chrome plated brass. The stainless steel models are generally regarded as higher quality, but cost a little more. Both types use NSF-61 approved neoprel inserts.
