Astandardfail‐closeactuatorassemblyisfirstinstalledinthepiperuninthedirectionofflow.
ThedeviceisthenconnectedtotheHON P095NGpilot,whichinturnisalsoconnectedtothe
regulatingline’sinletandoutletpressures.Together,theactuatorassemblyandthepilot
makeupthemonitorregulatorunit.
Downstreamofthissetup,afail‐openactuatorassemblyisinstalledwithaHON P095NGpilot
aswell.
TogetherwiththeHON P095NGpilot,thissecondactuatorassemblymakesuptheactive
regulatorunit.
Theoutletpressureismonitoredbytheupstreammonitorregulatorunitinadditiontothe
activeregulatorunit.Thesetpointonthemonitorregulatorunitissettoavaluehigherthan
thesetpointfortheactiveregulatorunitbeingcontrolled,whichensuresthatthemonitor
regulatorunitwillnormallybefullyopen.Intheeventofmalfunction,theactiveregulator
unitopensaccordingtothefail‐openprinciple.Assoonasthesettargetvalueofthemonitor
regulatorunithasbeenreached,itstartsregulatingtheoutletpressure.
