For water treatment processes such as ultrafiltration UF and reverse osmosis RO, which are similar to sequential control devices, what is the power supply type for the pneumatic butterfly valves and solenoid valves used on site?
Thread Content
Those who have maintained such sequence control devices should be familiar with the on-site conditions. To meet the requirements of the process equipment, there are numerous pneumatic butterfly valves in use for tasks such as water intake, drainage, backwashing, and air supply. Which type of solenoid valve results in less maintenance effort – those operating at 24VDC or those operating at 220VAC? We chose the Taiwan Yadake 220VAC model here, and I feel its failure rate is quite low. Moreover, I think in an industrial environment like water treatment, using AC solenoid valves might be more suitable Friends with relevant experience, please join in the discussion!
In terms of failure rate, 24V is lower; furthermore, 220V is more difficult to maintain
Which RO do you use? It seems similar to the one installed in my previous workplace. Is it possible to take a photo to take a look?
Are the butterfly valves from Beijing Huayang made by Bore?
The same; is the P pipe made of PVC?
That’s right! The pipes are all lined with plastic!
Desalination plant? ? ? We use 220VAC here
UF\RO system: SMC solenoid valves together with a base plate; powered by DC24V. Installed in the solenoid valve cabinet. PU air supply hoses lead to the valves on site. Borel S29/30 series of wafer-type pneumatic butterfly valves. The solenoid valves have an extremely low failure rate
The S30 is Bore’s rubber-lined butterfly valve, right? Does it often experience sticking issues, making it difficult to operate?
