Brass Critical Purity Regulators Model ASGEAG3800100 DEL PRESS 10-100 PSIG

Metal Diaphragm Seal, Brass and Stainless Steel 

Models AG3800, AG3805, AG3810 

These regulators are designed for critical and ultra-high purity gases in line applications at inlet pressures up to 3000 psig. The all 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 minimal internal volume for maintaining guaranteed gas purity levels. Models AG3800 and AG3805 are for noncorrosive gases; Model AG3810 is suitable for use with most corrosive gases. 

Standard Features 

n Metal-to-Metal Diaphragm to Body Seal (without back-up o-ring) assures maximum diffusion resistance. 

n Regulator Design permits vacuum purging of regulator. 

n In-line Porting permits direct installation of regulator in piping system. 

n Filter traps foreign matter, extends regulator life and reduces maintenance. 

n Threaded Holes in Rear of Regulator permit front panel mounting.
