Motorized valves are typically used to control a single function and offer limited or no capabilities to provide multiple electronic functions with hydraulic backup functions. On the other hand, hybrid electronic and hydraulic control valves can reduce the number of valves required in a system and can offer useful “insurance” against power failures and costly line breaks.
Below are three scenarios where this combination proved to protect systems during power outages.
Scenario 1 – Hybrid multifunction electronic and hydraulic metering valve
When a power failure occurs, there is an arduous and lengthy process that water treatment plant operators need to perform quickly in
