The Dival 600 series gas pressure regulators are direct-acting devices controlled by a diaphragm and opposing spring, designed for low, medium and high-pressure applications. The modular design allows integration of an emergency shut-off mechanism or configuration as an in-line monitor within the same body, without altering its face-to-face dimensions. The true top-entry design facilitates easy periodic maintenance without removing the regulator body from the pipeline. The features of the Dival 600 series regulators make them suitable for a wide range of applications.
