Industrial HN491S3331413 Needle Valve Regulator

Industrial HN491S3331413 needle valve regulator provides precise pressure regulation for high-pressure lines, combining a finely adjustable needle valve with a regulator function. It is rated to 6580 psi and terminates with a 1/2 in NPTF connection, making it compatible with standard high-pressure fittings in many industrial systems. The model designation HN491S3331413 identifies this specific configuration, designed to deliver stable output in demanding environments where exact control of flow and pressure is essential. This compact regulator supports slow, controlled throttling of high-pressure gas or liquid flows, enabling gradual pressure adjustments and reduced fluctuation in instrumentation loops or test setups. With its industrial build, it is suited for applications that require precise regulation at high pressures, such as calibration rigs, pressure testing, and process control lines where reliability and repeatable performance are critical. Its rugged construction supports repeated cycles and stable performance under demanding conditions.
