MEA EMERGENCY SHUT DOWN SYSTEMS (ESD)
FOR EMERGENCY SHUT DOWN AND TRIP VALVE TRIGGERING
2 OUT OF 3 EMERGENCY SHUT DOWN SYSTEM
MEA is proud to introduce our new 2 out of 3 (2oo3) voting system for operation of trip and Emergency Shut Down (ESD) valves. Our 2oo3 system can be included on all of MEA’s control and actuator products from Eagle hydraulic power control units to Hawk self-contained electro-hydraulic actuators to two-position ESD skids. The system can even be retrofit to existing actuators, whether from MEA or other manufacturers.
- To trigger ESD function any 2 out of 3 solenoids valves must deenergize
- Operates independent from the control system
- Response time <100 msec
- ESD speed of operation as low as 0.3 seconds
- Individual pressure ports for individual solenoid testing
- Hazardous area rated
