Close-Off Ratings
a - VB-8xxx - First value = maximum close off pressure, Second value = maximum operating differential. (Example: 125/35).
b - VB-9213/VB-9223 2-Way valves have the same close offs as VB-9313 valves.
c - VB-8xx3 valves use AV-497 linkage, VB-9313 valves use AV-495 linkage.
d - AV-607-1 (2 ½" - 5" VB-8000 valves or 2 ½" - 4" VB-9313 valves), the Mx41-634x actuator is not compatible with the AV-607-1
linkage.
e - AV-609-1 (6" VB-8000 valves or 5" - 6" VB-9313 valves), the AV-609-1 linkage can be used with the Mx41-634x actuator on 2 ½"
- 5" VB-8000 valves or 2- ½" - 4" VB-9313 valves, but the valve will stroke over a shorter portion of the control input signal
