TOTAL VALVE SOLUTIONS
Both pressure and flow velocity must be considered when designing reservoir level control systems. Pressure considerations for reservoir inlet control valves. For reservoir level control valves, anything above 4 to 5 bar is high pressure. Pressures above 6 to 8 bar can be disastrous for control valves if precautions are not taken. This is because…
DetailsStandard pilot-operated globe control valves are often specified for level control. But, they are not suitable in some installations:- In low pressure installations (below 1.5 bar dynamic pressure). When dirt particles in the water might clog small orifices. Where they might be subject to vandalism. A diaphragm valve offers several advantages in these cases:- They…
DetailsWe have a professional responsibility to consider the total cost of ownership of equipment we specify. Sometimes the lowest up-front price ends up being the most expensive. This is especially true for air valves. Air valves make up a tiny part of the capital cost of a pipeline but they’re often the cause of significant…
DetailsFor most engineers the criteria for selecting control valves is confusing. Usually they end up specifying a control valve promoted by the last representative who met with him, or the company with the most prominent marketing. This often results in valves selected with less than suitable features for the applications they are chosen for. An…
DetailsThe following article was written by Alan Sunudo of A.R.I. Flow Mexico and republished here with permission. It’s well known that pumps and pipelines are our most valuable assets in fluid transmission systems. So why not choose the right devices to protect those components against abrupt changes in velocity, thus in pressure than can lead…
