Butterfly valve, as one of the basic kinds of successful valves, has been widely used in many fields. It is basically connected to reach on-off channeling and flow control. In general, it has been important in the fields of petroleum, the industry of substances, metallurgy, electricity and water, etc. With expanding requirements and complex working conditions, it is not possible to use current ...
In this study, an algorithm is presented for pipe system diagnosis. The algorithm is the Successive Linear Estimator (SLE) previously used in groundwater hydrology to estimate the hydraulic proprieties of soils. The SLE is an iterative cokriging-like technique which provides statistically the best unbiased estimates and quantifies the associated uncertainty. In this paper the algorithm has been ...
A model to support decision systems regarding the quantification, location and opening adjustment of control valves in a network system, with the main objective to minimise pressures and consequently leakage levels is developed. This research work aims at a solution that allows simultaneously optimising the number of valves and its location, as well as valves opening adjustments for simulation in ...

Patoka Lake Regional Water & Sewer District (PLRWSD) serves 11 counties in southern Indiana with a population of around 130,000. The distribution of water travels through approximately 850 miles of pipe ranging in size from sizes 3 to 30 inches and includes numerous elevated towers or tanks in each District Metered Area (DMA). The treatment facilities are fed by an intake structure located ...
Around the world there is a growing need for automated valve control in remote locations where mains electrical power is not available. For example, effective water management demands efficient and responsive flow control for applications such as groundwater remediation, irrigation and flood prevention. With perceived climate changes introducing more extremes of rainfall or drought conditions, ...
Regular maintenance ensures valves remain healthy. If your system is operating properly, you should physically inspect all valves at least every 12 weeks to check for tubing leaks and other abnormalities. Pressure gauges should be checked to ensure each valve is performing as designed. If you find something wrong, refer to the appropriate instruction manual, which may be available online. ...
Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. For a correlator to highlight a potential leak each sensor must be able to receive the signal from that leak. Once a correlation is highlighted it is then down to the software and the user of the ...
Solenoid Valves are used throughout a number of industries, due to the valve’s versatility. Solenoid valves can be used with either fluid or gas applications, making them favourable among a number of manufacturers. Solenoid valves use an electromechanical magnetic field which opens and shuts the valve, making the valve a reliable option for pneumatic and hydraulic systems. WHAT ARE THE ...
