Remotely Operated Shut-Off Valve (ROSOV) is a type of Emergency Shutdown Valve (ESDV) which allows a plant or facility to be isolated automatically from a safe location without the necessity for manual intervention that is designed and installed for the purpose of quickly isolating plant items which are used for the storage of hazardous substances. In the Remote Operated Shut-Off Valve (ROSOV) scenario, in an emergency shutdown the actuator will immediately return to the predetermined safe position and will be ready to operate on the next command when the ESD signal is reinstated.
