Parker Pneumatic
P3BA45 Pneumatic Input Signal Amplifier – Precision

Key Features

  • Five signal to output ratios meet most control element requirements.
  • Control sensitivity of water column allows use in precision applications.
  • Large Supply and Exhaust Valves provide high forward and exhaust flows.
  • Soft Supply and Exhaust Valve seats minimize air consumption.
  • A balanced Supply Valve minimizes the effect of supply pressure variation.
  • An Aspirator Tube compensates downstream pressure droop under flow conditions. 
  • A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
  • Optional remote feedback port minimizes pressure drop at final control element under flow conditions.
  • Unit construction lets you service the P3BA45 without removing it from the line.
