The ECONTROL Emergency Shut Down Valves (ESDV, ESD, ESV, SDV) are used to isolate pressure and flow from a particular source during an overpressure situation or detection of a dangerous event. ESD valves are integrated into the plant system equipment design and can be installed upstream, midstream, or downstream.

The emergency function is always initiated by an ESDV, helping to avoid catastrophic damage to plant, personnel, or environment. ESDVs form a critical part of Safety Instrumented Systems, and ECONTROL has been a pioneer of Functional Safety integration for over three decades.
