Frequently Ask Questions
A High Pressure Emergency Shut Down Valve (ESDV) is an automated isolation valve designed to rapidly shut off high-pressure process flow during emergency conditions such as leakage, pressure surges, fire or equipment failure.
A spring-return actuator can provide a predetermined fail position when the operating air or control energy is lost. This is useful for emergency isolation systems.
The primary purpose is to quickly isolate a hazardous or high-pressure section of a process system to help limit the release of process media and protect equipment and personnel.
