VB
Volume Booster
Economical, 1:1 Ratio
he Series VB Volume Booster is a one to one signal to output relay and an ideal
T
solution to increasing valve stroke speed. A large input signal change to the booster delivers
high volume for quick throttling control. Volume booster responds to the slightest changes
in input signal, which in turn increases accuracy of the output of air pressure to the actuator.
his booster receives the positioner’s signal output and supplies the proper air pressure to
T
the actuator to reduce response and adjustment time. Available in aluminum or stainless
steel.
