Maximum Static Pressure is 10 bar .
Recommended maximum flow velocity in pipelines is 2 metres/second.
Maximum Pressure Loss Ratio*: should not exceed 10:1, in favour of either supply,
during flow.
Recommended Maximum Dynamic Supply Pressure: 5 bar.
Maximum Static Supply Pressure: 10 bar.
Recommended maximum flow velocity in pipelines is 2 metres/second.
* Pressure Loss Ratio is determined by subtracting the resistance to flow of the outlet
pipework and outlet fittings (generally known as "back pressure", and measured at the
outlet of the mixing valve) from the dynamic pressures of the hot and cold water at each
inlet of the mixing valve. This is at its extreme when the mixing valve is being used at
its lowest flow-rate and when the maximum inequality occurs in the pressure of the hot
and cold water supplies.
