NOTES:	(1) When using an instrument such as a positioner or controller with a 3-15 PSI (0.21-1.05 BAR) input signal use the 0 to 20 PSIG column (Light Spring).
	(2) For valve use where downstream pressure exceeds 2,750 PSIG (190 BARG), 2,750 PSIG should be used as the Maximum Shut-off Pressure.
	(3) Do not exceed the Pressure Temperature Limitations as per ASME B16.34.
