Adjustable Fixed Flow Regulator Series 3980

The 3980 series provides the control of the single fixed flow regulators with the advantage of being able to change flow rates as required for different applications. This regulator eliminates the need to have multiple regulators on-site. There are models suitable for use with non-corrosive gases and mildly corrosive gases. Commonly called the “click” regulator it has 12 flow positions, OFF, 0.3, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 5.0, 6.0, 7.0, and 8.0 slpm. NOTE: Flow rates are estimated. Actual flow rates will vary depending on gas service and pressure.

Features

• Adjustable delivery pressure.
• Integral needle valve for shut-off and to control flow.
• Integral CGA 600 connection provides compactness and minimal loss of gas during installation and removal.
