Automatic low-cost regulating valve
This valve operates without auxiliary energy. It keeps the flow rate of fluids constant with great accuracy (± 0.2 L/min) regardless of fluctuating inlet pressure, using an impressively simple but unique principle. The constant flow is generated by the two stainless steel spring plates of the so-called regulating orifice being riveted together across each other and which, depending on the differential pressure, open or close to a greater or lesser extent the ring or regulating funnel thus created. For the most extreme differential pressure (around 10 bar) the flexible regulating orifice is in complete contact with the regulating funnel so that only the rivet hole cross section is available for flow and from this point the valve operates as a fixed orifice. The REG flow limiter can be used wherever a constant flow rate is required inspite of pressure fluctuations in the system, such as when for example switching a consumer unit on and off. To clarify further, imagine yourself standing under the shower in a hotel in the morning. What usually happens when other hotel guests start to shower at the same time? The water temperature suddenly changes from pleasant to horribly cold or unbearably hot; sometimes there is less water flowing sometimes there is more; the day has hardly begun but it starts with a basically avoidable annoyance. It would be avoidable, if the planners had thought beforehand to install our simple flow regulator.
It is not only in the sanitation and heating fields that unwanted fluctuations in flow and temperature occur, but also in many areas of general industry and plant construction. The valves are available in brass and stainless-steel. Regulators as individual elements with internal or external 1/2"and 3/4" threads are available for 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 25, 30 and 40 L/min of fluid. To regulate larger flows several elements are mounted on a common disc.
