Pressure builders (PB series)

  • Two 1/4” FNPT delivery pressure gauge ports are located (plugged) on each side of the valve
  • Large seat and diaphragm areas provide high capacity with sensitive control of delivery pressure with low falloff
  • T-handle adjusting screw
  • Two bonnet drain/vent holes to allow for different mounting orientation
  • Cleaned for oxygen service per CGA G-4.1
  • 100% Factory tested

High precision of pressure control and flow capability is beneficial for applications with specific requirements. Removing liquid from the bottom of a tank and passing it through a coil is how the regulators build pressure.
