The Integral Volume Booster accessory for the Sipart PS2 electro-pneumatic valve positioner is designed for pneumatic actuators that require high flow for fast stroking times. It reproduces pneumatic signals in a 1:1 ratio for applications requiring increased flow capacity, while maintain small step accuracy and reducing piping requirements. The booster directs a high volume air supply to the actuator. This feature eliminates the complex piping and additional fittings required with external volume booster devices. The new valve accessory also uses an internal bypass for small step changes, which reduces overshoot and ensures accurate positioning.
