 p3ba45-pneumatic-input-signal-amplifier

FEATURES

  • 1/2" and 3/4" ports (NPT, BSPP)
  • Pneumatic input signal for accurately controlling output pressure based on a predetermined ratio
  • Large supply and exhaust valves provide high forward and exhaust flows
  • Soft supply and exhaust valve seats minimize air consumption
  • Optional remote feedback port minimizes pressure drop at final control element under flow conditions
  • Optional adjustable bypass valve (1:1 ratio only) lets you tune for optimum dynamic response
