Dival 600 series pressure gas regulators are direct-acting devices for low and medium pressure applications controlled by a diaphragm and counter spring.

The modular design of the Dival 600 series pressure regulators allows the installation of an incorporated slam shut or device for use as an 'in line monitor' on the same body without changing the face-to-face dimension.

Furthermore the truly 'top entry design' allows easy regular maintenance without removing the unit  from the line. The features of Dival 600 series regulators make them a product suitable for any application.
Features
  • Accuracy Class: up to 5
  • Available Size DN: 1″, 1-1/2", 2″
  • Closing Pressure Class SG: up to 10
  • Design Pressure: up to 20 bar
  • Design Temperature: from -20° to 60° C
  • Flanging: Class 150 RF According to ASME B16.5 and ASME B16.42, Class ANSI 125 FF According to ASME B16.1, PN 16 and 25 According to ISO 7005-1 and ISO 7005-2
  • Minimum Working Differential Pressure: 0.1 bar
  • Outlet Pressure Range of Wd: from 12 to 4,400 mbar
  • Range of Inlet Pressure bpu: from 0.1 to 20 bar
