Self closing metered taps

Water saving self closing metered taps are used in a wide range of applications.  Especially in industrial applications where water saving forms part of the policy of the company. Self closing taps are also ideal for schools, sports arenas and public ablutions.  They are also often used in factories where workers need to operate tools with both hands while using water and the assurance that the water will shut off makes operation just easier.

The self closing metered taps will supply water for up to 8 seconds after which it will automatically close.

Metered taps differ from demand taps. Demand taps supply water when the tap button is pressed. Once it is released the valve shuts.

Self closing metered taps are used on the following industrial basins and wash troughs

  • Oval A, Oval B and Oval KA – (M-100M, W-420, W-220 and W-100R)
  • CHBC combination sluice sinks – (M-100M, W-420, W-220 and W-100R)
  • All wash troughs – (W-101R)
  • FSW & FSWSB industrial hand wash basins (W-101R)
  • Undercounter hand wash basin – (M-100M, W-420, W-220 and W-100R)
  • SIRX range of combination wash troughs – (W-101R)

Calderoni metered basin pillar mixer

The Calderoni metered pillar mixer is suitable for commercial and industrial use. Made from DZR brass so it will last much longer than standard brass taps. The taps flow time can be adjusted between 2-40 seconds ±10 seconds depending on the water pressure. flow rate is also adjustable to compensate for basin design and or water supply volume. Ideal operating pressure is between 2-4 bar. Water temperature is set on the small lever to the side of the pillar tap.

Self closing metered tap with hot/cold mixing

The metered pillar tap with temperature control is unique. Most industrial and commercial metered taps provide either cold water or pre-mixed water with an external thermostatic valve like the  Rada Meynell 15/3 or GR-34487.  This metered pillar tap has internal hot and cold water temperature regulation that saves money and reduces installed components. It makes installation much easier.

The GR-GR-36265000 is the same tap but without hot and cold mixing. So it uses cold water only or pre-mixed water with a thermostatic valve.

The pillar tap can only be used with pressurized geysers. Gravity fed geysers will not work as the minimum operating pressure is 0.5 bar. A gravity geyser coupled with a pressure pump will also work.
