Industrial 4ZM14 Pneumatic Regulator 300 PSI Max

The Dayton/Speedaire 4ZM14 Pneumatic Regulator is a compact inline pressure regulator designed to maintain stable downstream air pressure in industrial and commercial pneumatic systems. It tolerates up to 300 PSI maximum operating pressure, regulates from 5 to 150 PSI, and supports up to 80 CFM, with 1/4 in. FNPT inlet and outlet ports (NPT); the pressure gauge port is 1/8 in. NPT and a gauge is not included. The regulator uses a nonrising knob adjustment, a balanced valve design, and a rugged aluminum and zinc body rated to 150°F, with overall dimensions of 4-3/16 in. high and 2 in. wide for tight installations. Commonly used in air compressors, pneumatic tools, assembly lines, packaging machines, and other industrial automation applications where steady downstream pressure is critical; it is suitable for replacement or retrofit by maintenance teams, OEMs, and system integrators. Related replacements include Speedaire 4ZM14, Parker 14R Series, and Norgren R07 Series.
