Parker Standard High Precision Relief Valves | P3RA102BP Series


 p34a102-standard-high-precision-regulator
The P3RA102BP is a high capacity relief valve that relieves excess pressure in a pneumatic system. It provides greater accuracy than standard relief valves over a narrow pressure range and can be used for a wide range of precision applications.

FEATURES

  • 1/4" ports (NPT, BSPP)
  • Control sensitivity of .125" water column variation for use in precision applications
  • Separate control chamber and aspirator tube isolates diaphragm from the main flow
  • Unit construction allows you to service relief valve without removing it from the line
