Stainless Steel Regulators

Stainless Steel Gas Pressure Regulators for Specialty Gases

Stainless steel pressure regulators are designed for use with corrosive specialty gases and provide outstanding performance in applications involving high delivery pressure where maintenance of gas purity is essential. Single-stage is recommended where inlet pressure does not vary greatly or where periodic readjustment of delivery pressure setting does not present a problem. Two-stage is ideal when constant delivery pressure is desired.

Scott Models 213 and 215
Ultra-High-Purity Pressure Regulators

Scott Models 213 and 215 have stainless steel diaphragms that minimize diffusion of air into the pressure regulator and eliminates offgassing.

Scott Models 217 and 2172
Tied-Diaphragm Pressure Regulators

Scott Models 217 and 2172 tied-diaphragm pressure regulators resist attack from stong acid-forming gases and facilitate safe handling of corrosive, toxic and reactive gases with inlet pressures of up to 3000 psig (207 bar). Great for semiconductor applications.

Scott Models 217CP and 2172CP
Tied-Diaphragm Pressure Regulators with Cross Purge

Scott Models 217CP and 2172CP tied-diaphragm pressure regulators with cross purge assemblies are designed to resist attack from stong acid-forming gases. The cross purge assembly has three diaphragm packless valves and a check valve that are utilized during inert gas purging operations.
