/hr.- normal cubic meters per hour (0_C and 1.01325 bar, absolute); Scfh - standard cubic feet per hour (60_Fand14.7psia).
2. These terms are defined in ANSI/ISA Standard S51.1
3. Without snubber. If this actuator has a snubber, the temperature specification is the same for the nitrile version.
4. The pressure limits in this bulletin and any applicable standard or code limitation for actuator should not be exceeded.
