Altra Industrial Motion EN42120 Air Pressure Regulator

The EN42120 air pressure regulator from Altra Industrial Motion (Boston Gear) is a compact standard regulator designed to down-regulate compressed air to a stable downstream pressure in small-to-medium pneumatic circuits. It uses 1/4 in NPT inlet and 1/4 in NPT outlet ports in a straight configuration and provides a set-pressure range of 5–100 psi (maximum set pressure 100 psi) with a relief-type control and a non-rising knob; a panel-mount option is available. The regulator operates with air as the working fluid, handles supply pressure up to 300 psi (125 psi proof), and is rated for 0–150 °F operation, weighing about 0.32 lb with overall dimensions of 1.50 in length, 1.63 in width, and 2.93 in height; inlet/outlet port sizes are both 1/4 in, with straight port geometry and female port gender, and gauge is not included.
