neqsim.process.instrumentdesign.InstrumentDesign

neqsim.process.instrumentdesign.valve.ValveInstrumentDesign

All Implemented Interfaces:

Serializable

public class ValveInstrumentDesign
extends InstrumentDesign

Instrument design for control and safety valves.

Determines the required instrumentation for a valve. Typical instrumentation includes:

• Position: ZT (valve position transmitter)
• Positioner: ZC (I/P converter or digital positioner, AO)
• Solenoid: XV (trip solenoid for ESD valves, DO)
• Limit switches: ZSO (open), ZSC (closed)
