No more awful shower experiences

Starting the day off with a shower with unstable water flow and temperature could be avoided if the planners had thought beforehand to install flow restrictors/regulator that keeps constant quantities of liquids in pipework systems.

Kobold’s REG rate regulators (available in brass and stainless steel) are ideally suited for the simple restriction to a pre-set value of throughputs of water, or of liquids like water. The flow restrictors ensure equilibrium, particularly in systems with many users and resulting pressure fluctuations caused by random flow conditions. In other words, the desired throughput is not exceeded.

The REG valve operates without power supply, keeping the flow rate of fluids constant with great accuracy (±0.2ℓ/min) regardless of fluctuating inlet pressure. The principle is impressive, yet uniquely simple. The constant flow is generated by two stainless steel spring plates of the regulating orifice, 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 despite pressure fluctuations in the system, for example switching a consumer unit on and off.

Notable benefits

  • No auxiliary power required
  • Easy to assemble
  • Compact design
  • Reliable – no wearing parts
  • Energy-saving
  • Easy to fit

So, 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.
