P3BA208 Series Pneumatic Input Signal Amplifier

Brand: Parker Hannifin

P3BA208 is a pneumatic air volume booster that reproduces a low flow control signal with a higher regulated flow output pressure. It uses an unregulated input pressure to maintain a regulated output pressure under flowing and non-flowing conditions.

The P3BA208 is available in multiple predetermined ratios, thus providing user with a direct reproduction of the pneumatic control signal, a multiple of the pneumatic control signal, or a fraction of the pneumatic control signal.

The P3BA208 pilot input signal amplifier accurately controls output pressure bases upon a predetermined ratio. The input signal amplifier reproduces a low flow control signal with a higher regulated flow output pressure.

It uses an unregulated input pressure to maintain a regulated output pressure under flowing and non-flowing conditions. A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
Features
  • The P3BA208 uses a pneumatic input signal to accurately control output pressure based on a predetermined ratio
  • A balanced supply valve minimizes the effects of supply pressure variation
  • An aspirator tube compensates downstream pressure droop under flowing conditions
  • A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
  • Unit construction allows servicing without removal
  • Maintains regulated output pressure
  • Available in multiple ratios
