Answer Posted / joby

if the valve is in higher size ,we have to go for higher
actuators for operating the valve.
FOR ESD VALVES
if the valve size is more than 18" mostly the suppliers
prefer hydraulic systems for operating the actuator
instead of air.The pressure required to operate the higher
size actuator will not be sufficient ,if you are using
plant air.
