indicate complete assemblies. indicate close-off psi.
Close-off values are for 15 psi signal for Normally Open and 0 psi signal for Normally Closed.
Close-off values for Normally Open valves with positioner may be substantially higher based on line supply pressure.
High Temp actuator assemblies are not available. Valve and actuator sold separately and will have to be assembled in the eld
