Volume booster for electro-pneumatic valve positioner
Siemens' Integral Volume Booster accessory for the Sipart PS2 electro-pneumatic valve positioner reproduces pneumatic signals in a 1:1 ratio for applications requiring increased flow capacity while maintaining accuracy.
Siemens Industry introduces an Integral Volume Booster accessory for the Sipart PS2 electro-pneumatic valve positioner is designed for pneumatic actuators that require a high volume flow of air supply to the actuator. This feature is designed to eliminate the complex piping and additional fittings required with external volume booster devices. 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. Siemens Sipart PS2, which is 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, this combination provides a low bleed rate designed to decrease the total cost of ownership. The valve accessory also uses an internal bypass for small step changes designed to reduce overshoot and ensure accurate positioning.
