Valve Install Instructions

VG7000 Series Bronze Control Valves Product Bulletin14
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 VA-715x, VA-720x, and VA-8x2x are not available factory coupled for PDTO two-way. These are available for field
mounting only.
3. 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.

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 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.
