Why we use the double acting control valve in flow line?
Answer Posted / carl_ellis
Part of your problem is your terminology.
Valves are chunks of machined metal and elastomers, valves
are not single action or double action, the actuator that
moves the valve stem is.
So your Google search should be for double action actuator,
which will provide you an answer.
