Series 120

The Series 120 are general purpose two stage regulators recommended for control of inert and noncorrosive pure gases in laboratories, general plant and maintenance shops where constant delivery pressures are required.

These regulators are not recommended for applications where inboard diffusion of air or outgassing of elastomeric components would adversely affect the work being done. A preset safety relief valve vents to atmosphere, which makes this regulator suitable for only nonhazardous gases.
