Who becomes the voice of the people and makes sure that these promises are kept? The U.S. Conference of Mayors plays a major role in not just ensuring that administrations “make good” on the promises, but in helping to shape infrastructure plans and make the most efficient, effective use of federal funding.

  • Is Your Head In The Clouds?
    Is Your Head In The Clouds?

    Every day you hear things like “push your data into the cloud” or the newest functions of “cloud computing”.  But what does this all mean? And what does it mean for utilities and facilities? Well, if you’re looking into Cloud SCADA, it can mean then difference between having to purchase and maintain software and hardware versus utilizing the internet and cloud computing platforms to serve as the framework for your SCADA system. That translates into time and money saved in the long run.

PRODUCT GUIDE

Pneumatic Dynamic Lifter Relief Valve Pneumatic Dynamic Lifter Relief Valve

The Pneumatic Dynamic Lifter is a very responsive compact wastewater relief valve that can handle high pressures and uses a compressed air cylinder to hold the valve closed. This chamber is fitted with a relief pilot that is normally closed as long as the line pressure is lower than the set point. If pressure rises above the set point, the relief pilot opens, causing the air in the cylinder to vent, which in turn opens the valve. The valve closes drip tight when pressure falls below the set point.
