P3BA208 Series Pneumatic Input Signal Amplifier
Brand: Parker HannifinP3BA208 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
