PF Dival 600 Direct-Acting Gas Pressure Regulators

Dival 600 series pressure regulators are direct acting devices for low and medium pressure applications controlled by a diaphragm and counter spring.
These regulators are suitable for use with previously filtered, non corrosive gases.

The modular design of the Dival 600 series allows for the addition of a slam shut or an in-line monitor device in the
same body without changing the face-to-face dimensions. The truly “top entry design” allows easy periodic maintenance without removing body from the line. The features of Dival 600 series regulators make it a product suitable for any application.
The fast response time makes it ideal for burner or industrial applications or whenever sudden changes of flow rate is part of the process. The high accuracy against any inlet pressure variation makes the Dival 600 series an optimum product for gas district systems, an application generally not suitable for direct acting regulators.

Extremely easy maintenance and reduced number of parts lower operating expenses and labor.
