Non Revenue Water Control By P26U Pressure Management valve Switch Pressure Based On Instant Flow Rate
Description:
P26U can switch two sets of pressure based on instant flow rate. It helps to manage the pressure in when flow rate demand varies.
Benefit:
1. Energy Saving
2. Water Saving
By managing the pressure in water distribution line, the leaking from pipeline can be controlled well by killing the redundent pressure.
Service Fields:
For water system, irrigation system.
Technical Data:
IP68 for water resistance
Comply with BS EN 1074-5, ISO 5208, BS
EN 12266-1, BS EN 558-1
