Integral volume
booster valve
accessory
Siemens Industry has introduced an Integral Volume Booster
accessory for the Sipart PS2 electro-pneumatic valve
positioner, designed for pneumatic actuators that require
high flow for fast stroking times.
The Integral Volume Booster reproduces pneumatic signals
in a 1:1 ratio for applications requiring increased flow
capacity, while maintaining small step accuracy and reducing
piping requirements.
It couples with the Sipart PS2 valve positioner, and directs a
high-volume air supply to the actuator.
This feature eliminates the complex piping and additional
fittings required with external volume booster devices.
Siemens Sipart PS2, used to control the final control element
of pneumatic linear or part-turn actuators, has a low bleed
rate, and when paired with the Internal Volume Booster, the
combination provides a low bleed rate.
The Integral Volume Booster provides a Cv of 2.0, offering
users the performance and accuracy needed to operate large
valves and actuators.
The new valve accessory also uses an internal bypass for
small step changes, which reduces overshoot and ensures
accurate positioning.
