TOTAL VALVE SOLUTIONS
Pressure management has become a crucial tool to reduce water losses in pipe networks. It brings almost instant results at a relatively low cost. The theory is that if you reduce the pressure in a network to the lowest practical pressure:- But, it’s not set-and-forget. Presures must be adjusted to match flow demands. Electronic pressure…
DetailsSay “pressure reducing valve” to someone in the water industry and they’ll assume you’re referring to a complex pilot-operated valve, something like the one in the picture below. Pilot operated pressure reducing valves allow for bolting on controls for remote operation, automatic flow rate limitation and upstream pressure sustaining. You can end up with something…
DetailsBoth 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…
