VALVES
The Series VB Volume Boosters are 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.
BENEFITS/FEATURES
• Responds to the slightest change in input signal
• Supplies constant air pressure at a 1:1 ratio
APPLICATIONS
• Used with pneumatic control valves
