To Wire or Not to Wire?
Wireless control and monitoring of valves and other critical systems has never been more debated. Valve Magazine proclaims a bright future for wireless technology. Proponents point to real-time data sharing, lower installation and maintenance cost, flexibility in valve placement, and other benefits. But, is there a downside to wireless? And, is there still a place for manual, standalone valves?

Parallel Pump Control Conserves Water
To reduce the leakage of drinking water from aging European pipelines, Grundfos has engineered a control system to regulate pipeline pressure of several small pumps arranged in parallel, rather than using one big pump to maintain pressure. The pumps can be turned on and off as needed, resulting in lower pressure and less water waste.

Coating Yields 38-day ROI
Apply Wilo's Ceram CT coating to impeller blades, the inner contour, and inside the stage housing of water-supply pumps to improve efficiency two percent, and also protect against ochre formation. Wear resistance improves, too. ImpellerNet has published an ROI analysis that easily justifies the investment.

Multi-zone Flow Removes Nitrates
An ion exchange system removes nitrates from groundwater through constant four zone movement. By continuously moving groundwater, nitrate removal uses less energy. A multi-port valve is used that has a process disc with channels machined into its body. The channels separate and direct flow through the adsorption, displacement, regeneration, and regeneration rinse zones. [A short registration may be required.]

Opinion: How to Make Motors Live Longer
In this Reliable Plant article, experts from two of the largest motor manufacturers give their opinion on what end users can do to maximize motor life. The first bit of advice recommends that you focus on lubrication and temperature. The second opinion strongly suggests that you check to see if there's any contamination and water getting inside the enclosure. Read about where they agree and differ.

Intelligent Irrigation
To minimize water loss, a Colorado irrigation company upgraded five miles of open ditch irrigation canals with piping, flow meters, and two butterfly valves at each customer location. The company controls the first valve to deliver water to customers. The customer controls the second valve to shut-off or reduce water volume.

Water Plant Automates Water Flow
A South African water treatment plant adopted complete process automation. Valves are controlled by multi pin circuit board terminals that use only one cable per terminal. According to SA Instrumentation & Control, the solenoid terminals are also less prone to weathering and corrosion compared to actuated mounted solenoid valves.
