Specifications
Input Signal
Positioner output
Maximum Input Signal Pressure
(1)
VBL-1 and VBL-3: 5.5 bar (80 psig)
VBL-2 and VBL-4: 10.3 bar (150 psig)
Input to Output Pressure Ratio
Fixed at 1 to 1
Supply Pressure Ranges
(1)
When used in conjunction with a positioner or other
pneumatic accessory, always pipe the positioner and
booster with one common supply through a Fisher
67D, 67DR, or 95H regulator (see figure 2). A
high-capacity filter, such as the Fisher 262K, should
be installed in the supply line to the regulator. Supply
pressure also must not exceed the maximum
pressure rating of the actuator.
