The Series VB Volume Booster is a one to one signal to output
relay and an ideal 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. This booster receives the positioner’s signal
output and supplies the proper air pressure to the
actuator to reduce response and adjustment time. Available in aluminum
or stainless steel.
