Stainless Steel Two-Stage Regulator Model APG
STAINLESS STEEL REGULATORS
Model APG
Ultra High Purity, Two-Stage, Bar Stock Regulators

The Model APG stainless steel bar stock regulator is specially suited for applications requiring both corrosion and diffusion resistance in a two-stage regulator. It is recommended for high purity gases or gas mixtures that have corrosive properties. The two-stage design provides constant outlet pressure regardless of changes in cylinder (inlet) pressure.

Standard FeaturesStainless Steel Two-Stage Regulator Model APG
  • Type 316 Stainless Steel Bar Stock Construction provides maximum corrosion resistance.
  • Metal to Metal Diaphragm to Body Seal (without back-up o-ring) assures maximum diffusion resistance.
  • High Purity Regulator Design permits vacuum purging of regulator.
  • Diaphragm Seal Outlet Valve maintains gas purity.
  • Filter traps foreign matter, extends regulator life and reduces maintenance.
  • 1?16" NPT Female Bonnet Vent Ports allow bonnets to be connected to a vent line or disposal system as a precaution in the unlikely event of a diaphragm failure.
Optional Features
  • Captured Venting Configuration provides 1?16" NPTF vent ports and stem packing allowing for complete
    capturing of second stage bonnet when connected to a vent line or disposal system.
  • Mounting Ring permits regulator to be panel mounted.
  • Quick Mount Assembly provides for convenient and safe wall-mounted installation.
  • Internal (Inboard) Helium Leak Test and Test Report determines inboard leak rate of gas from regulator to
    atmosphere; test report certifies leak rate of less than 2 x 10-8sccs air equivalent.
  • External (Outboard) Helium Leak Test and Test Report determines outboard leak rate of gas from regulator to atmosphere; test report certifies leak rate of less than 5 x 10-7 sccs air equivalent.
