Part numbers in green indicate complete assemblies. Black numbers 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.
