dear,
I am wondering if it is preferable to use electrical motorized valves or pneumatic valves for the sand filters in water treatment plants. I am tending toward believing that electrical motorized valves seems better since they will not need any compressed dry air as the pneumatic valves. Any thought on this?
thanks a lot!
