TOTAL VALVE SOLUTIONS
One of the most common applications for self-actuated control valves is reservoir level control. At first glance it looks simple – exactly like a toilet valve. Except that toilet valves aren’t likely to fail from cavitation. I’ve written about combatting cavitation by controlling flow rates through level control valves. The article is here if you’re…
DetailsA pipeline needs one or more scour valves so it can be drained – usually for maintenance or repair. When a scour valve is opened, water is expelled from the pipe because of the difference between the pipeline pressure and atmospheric pressure. This can cause a very high flow velocity through the valve. Consider for…
DetailsSouth Africa and other countries on the African continent are running out of water! The volume of water unaccounted for (and unpaid for) is one of the highest in the world. Reducing water loss starts a virtuous circle that leads to less water loss:- Pressure management at the network level is often suggested as a…
DetailsPressure 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…
