Parker Standard High Precision Regulators | P3RA102 Series


 p34a102-standard-high-precision-regulator
The P3RA102 regulator is designed for applications that require high capacity and accurate process control. A poppet valve which is balanced by a rolling diaphragm ensures a constant output pressure during wide supply pressure variations. Stability is maintained with an aspirator tube which adjusts air supply in accordance with flow velocity.

FEATURES

  • 1/4" ports (NPT, BSPP)
  • Control sensitivity of .125" water column variation for use in precision applications
  • Pressure-balanced supply valve prevents supply pressure changes from affecting the setpoint
  • Separate control chamber isolates diaphragm from the main flow
  • Aspirator tube compensates downstream pressure drop under flow conditions
