1. The maximum closeoff pressure listed is limited to the maximum allowable ANSI valve body rating corresponding to the
maximum temperature rating (345 psig [2,377 kPa] at 281°F [138°C]) of the valve, except for VA-8x2x Actuators that are
limited to 195°F (91°C) maximum temperature and 381 psig (2,625 kPa) pressure rating.
The maximum closeoff pressures listed are for actuators coupled to the appropriate mounting kits listed in Table 7 and
Table 8. See Table 16 and Table 17 for valid factory-mounted combinations, and Table 7 and Table 8 for available field
mounting kits.
2. The maximum fluid temperature is 284°F (140°C) water to 38 psig (262 kPa) saturated steam except for the following:
VA-4233 Actuators are limited to 35 to 250°F (2 to 121°C) water to 15 psig (103 kPa) saturated steam.
VA-8x2x Actuators are limited to 195°F (91°C) water, and are not rated for steam applications.
