Parker Compact High Precision Regulators | P3RA302 Series


 p34a302-compact-high-precision-regulator
The P3RA302 regulator is designed for applications that require high capacity and accurate process control in a small package. A poppet valve which is balanced by a convoluted 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 .250" water column variation for use in precision applications
  • Compensating diaphragm allows regulator to remain unaffected by supply pressure changes
  • Aspirator tube compensates downstream pressure drop during flow conditions
  • Separate control chamber isolates diaphragm from main flow
