Speedaire 4ZM19 Pneumatic Solenoid Valve Industrial Air System

Speedaire 4ZM19 is an aluminum pneumatic regulator with 3/8 in NPT inlet and outlet ports, designed to stabilize downstream pressure in industrial air systems. It provides an adjustable output range from 5 psi to 150 psi and handles up to 208 CFM of flow, making it suitable for feeding air tools, cylinders, and other pneumatic actuators with consistent pressure. The regulator’s aluminum body offers corrosion resistance in typical workshop environments and compatibility with standard 3/8 in NPT piping and Speedaire components. In practical use, install the 4ZM19 downstream of the compressor or after an air-prep stage to deliver a steady, regulated pressure to valves, regulators, cylinders, and other pneumatic devices across manufacturing, packaging, and automation lines. For reliable performance, ensure all fittings are tightened and the source pressure remains within the regulator’s adjustable range, avoiding over- pressurization or leaks. As part of Grainger’s Speedaire line, the 4ZM19 provides a readily available solution for common 3/8 in regulator needs in industrial air systems.
