Orifice flow restrictor REG series

Mechanical flow restrictors REG from instrumentation specialists based in Hofheim am Taunus, impress with their simple and effective functionality. Once installed, the REG limits the flow to a preset fixed value, regardless of pressure fluctuations. Due to the high quality stainless steel design, the REG is completely maintenance-free. With no auxiliary power and secure from manipulation, the REG is particularly suitable for consumer applications and uniform supply to multiple consumers. In contrast to REG‘s stainless steel inserts, other manufacturers usually use a combination of rubber and metal discs, each with a round cavity in the middle. Water pressure compresses the elastic rubber disc, which changes the diameter of the cavity and thus regulates the flow; however, this only works as long as the rubber elasticity is intact! Due to temperature, chemical influence and aging, the molecular structure of the rubber strongly changes over time and as a result, the elasticity is lost, causing hardening of the rubber and therefore the flow cannot be regulated or guaranteed. This condition becomes problematic and above all expensive if this characteristic is underestimated or not pointed out. In contrast, our REG flow restrictors are designed for lifelong and maintenance-free use. Flow rate is kept constant with an accuracy of approximatly ±0.2 l / min, regardless of the fluctuating inlet pressure. Constant flow is realised by a so-called control orifice consisting of stainless steel spring plates followed by a ring or disc thereafter. Depending on the differential pressure,
