Class EnergizeESDValveAction

java.lang.Object
neqsim.process.logic.action.EnergizeESDValveAction
All Implemented Interfaces:
LogicAction
public class EnergizeESDValveAction extends Object implements LogicAction
Action to energize an ESD valve and open it to a specified position.

This action is commonly used in blowdown sequences where an ESD valve needs to be energized (powered) and then opened to allow emergency depressurization through a flare system.

Usage example: 

ESDValve blowdownValve = new ESDValve("BD-001", stream);
blowdownValve.deEnergize(); // Start closed for safety

ESDLogic esdLogic = new ESDLogic("Emergency Shutdown");
esdLogic.addAction(new EnergizeESDValveAction(blowdownValve, 100.0), 0.5);
