● Underwriters Laboratories, Inc. listed (file number
SA1089) for use with air, carbon dioxide, and inert
gases. For use with other gases, including oxygen,
consult Norgren.
● Compact design
● Brass, zinc, or aluminum bodies with plastic bonnet;
brass body also available with brass bonnet
● Plastic bonnet equipped with low torque, non-rising
pressure adjusting knob. Snap action knob locks
pressure setting when pushed in. Brass bonnet
equipped with pressure adjusting screw
● Non-relieving and relieving models. Relieving models
allow reduction of outlet pressure even when the
system is dead-ended
● Can be disassembled without the use of tools or
removal from the air line
