1. The maximum closeoff pressure listed is limited to the maximum allowable ANSI valve body rating corresponding to the
maximum temperature rating (308 psig [2,122 kPa] at 338°F [170°C]) of the valve.
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 VA-715x, VA-720x, VA-8x2x are not available factory coupled for PDTO two-way. These are available for field mounting
only.
3. The maximum fluid temperature is 338°F (170°C) water to 100 psig (690 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.
