In the case of fault, to ensure the safety of the system, it is often required that the valve be opened or closed in an emergency within 0.2 to 1 second. A control valve with this function is called a quick-acting valve. At present, the electric actuator can not meet this requirement, and only the pneumatic valve can be used to increase the emergency operation. As for the valve body, some forms should be taken into account according to the actual working conditions and can be selected among ten categories of regulating valves. For example, Fast action butterfly valve, fast action full-function ultra-light control valve, quick action single-seat valve.
