EMERGENCY SHUT-DOWN
SYSTEM (ESD)
Short Response Time
A short response time is essential for valves operating in Emergency Shut Down (ESD) systems
such as in refineries, power stations, mining and other applications where safety regulations
call for such.
The values in the table below indicate the closing time (seconds) of an unloaded actuator and
a loaded actuator with torque values simulating real-life situations. The stroke time measures
the actual movement of the actuator without a solenoid or any other accessory delay.
