Non Revenue Water Pressure Control Valve With Battery Controller installed
Non Revenue Water Pressure Management Valve Dual Adjustable Set Point Pressure Based On Instant Flow Rate Ductile Iron
Description:
In city with DMA management, water company can use Pressure Management Valve to control the pressure of each single isolated DMA and decrease the leakage without swapping the broken pipes. In such operation, water authority can decrease the leakage rate and NRW - Non Revenue Water issue.
P26U provide two adjustable pressure reducing pilots, one set to low pressure, the other to high pressure. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating relatively steady as the pilot set points. The high pressure pilot can be isolated by means of a battery operated latching solenoid. This solenoid is controlled using a fully programmable controlled which is user set to give higher and lower pressure based on instant flow rate.
Feature:
• Flow rate condition setting.
• Reduces system pressure when not needed (low flow demand), supplies increased pressure when required (high flow demand)
• Pressure Reducing Valve with two set points, high pressure and low pressure
Service Fields:
For water system, irrigation system.

Suzhou Alpine Flow Control Co., Ltd
Alpine Flow Control (SuZhou) Co.,Ltd with major focus in the water valve design and manufacturing. The Management staff have over 30 years experience in the water valve design and manufacturing, combined with the high-tech electronics manufacturing experience of multi-national listed companies. This unique combination of traditional and high-tech industry management experience and skills have given us an advantage over the traditional valve manufacturer. More than 40% of our staff are technical staff with knowledge and experience in valve and mechanical design/manufacturing...
Proven and supported by on-going quality and reliability test. AFC
has built it’s own in house reliability test laboratory to ensure
that our products not only meet the international quality and
reliability test specification such as the EN-1074-1/2 T-key and
R-key test, but also comply to various international valves
standards and specifications.
We already achieved WRAS certificate in 2011, and obtained FM
approval in early of 2012,
and UL for gate valve. Today, we have got many international famous
certificate for drinking water such as WRAS, NSF, AS, CE on certain
products, and our product range has expended to double eccentric
butterfly valve, rubber disc check valve ,non-slam check valve,
both clean water & sewage water air valve, hydraulic control
valve and penstock and we always focus on water system valves.
In 2018 year, our big plan is developing pressure management valves which has been proved to be a very helpful tool and economic way to save the leakage rate with limited investment and get a fast return in couple months and power savings
In addition, we have a special project team to focus on custom
design and special requirement
