A regulator’s lockup pressure refers to the pressure increase in the regulator’s outlet pressure above setpoint required to shut the regulator off tight. Most product documentation does not list expected lockup pressures because many of the factors that affect lockup are installation-dependent. Lockup pressures could be elevated when exposed to low temperatures, dirty process fluid, rapid on/off flow demand, small downstream volume, and aged elastomers. When troubleshooting an installation that appears to have higher than expected lockup pressure, first evaluate whether any of the before mentioned conditions could be causing the concern.
