Advanced Specialty Gas Equipment

Line Regulator Model AG3810 LINE REGULATORS
Models AG3800, AG3805, AG3810

Ultra High Purity, Standard Flow Line Regulators

The Models AG3800, AG3805, and AG3810 regulators are designed for ultra high purity gases used in line applications at inlet pressures up to 3000 psig. The metal to metal diaphragm to body seal design assures maximum diffusion resistance. Convoluted stainless steel diaphragms provide enhanced performance and excellent accuracy. These regulators are specially suited for point-of-use gas delivery systems requiring high leak integrity and guaranteed gas purity levels. Models AG3800 and AG3805 are for non-corrosive gases; Model AG3810 is suitable for use with corrosive gases.


Line Regulator with Optional Mounting PlateStandard Features
  • 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.
  • In-line Porting permits direct installation of regulator in piping system.
  • Filter traps foreign matter, extends regulator life and reduces maintenance.
  • Threaded Holes in Rear of Regulator permit front panel mounting.
Optional Features
  • Mounting Ring permits regulator to be panel mounted.
  • Compression Fittings installed in inlet and outlet ports allow connection to 1?4" or 1?8" tubing.
  • Regulator mounting plate allows for easy mounting of regulator to wall or panel.
