These measures to preserve the quality of the valve ensure its trouble-free operation and consequently, the reliable supply of drinking water for...

Hawido regulating valves – the right choice for every situation 1 Pressure reducing valves (outlet pressure control), Series 1500 The pressure reducing valve reduces a variable inlet pressure to an accurate and constant outlet pressure. Fluctuating inlet pressure and flow do not affect the regulated outlet pressure – this can be set as standard in the range 1.5 to 12 bar. Application In the drinking water sector, to supply the network and in emergency feeds Variants Electrically controlled, for two pressure stages as well as motor-controlled and combinations thereof Pressure relief and retention...
