Airgas Model 311C590 Brass-Plated Bar Stock Noncorrosive Gas Two Stage Regulator With CGA-590 Connection

These two-stage regulators are specifically designed for low-flow, non-corrosive gas applications where precise delivery pressure is critical. They feature a brass piston sensor in the first stage, a stainless steel diaphragm in the second stage and a preset safety relief valve. A sintered brass filter protects internal parts. These two-stage regulators are also ideal for medical diagnostic applications, such as blood gas analysis, where precise pressure control and low flow rates are required. They are available with a CGA-cylinder valve connection for use on large cylinders.
