  • Product Description
  • Dimension Drawing
The Fairchild Model 4000A is a non-bleed regulator that precisely controls a set pressure, and features a control sensitivity of 1/2" water column for use in precision applications. A pressure balanced supply valve prevents supply pressure changes from affecting the setpoint; and a separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.

  • Non-bleed design
  • Supply pressure ranges from 0-10 psig to 0-250 psig
  • Control sensitivity of 1/2" water column
  • Aluminum body and housing
  • Aspirator tube compensates downstream pressure droop
  • Can be serviced without removal from line
