Dival 500 Gas Pressure Regulator


The installation of the pressure regulator must occur in compliance with the provisions (laws or regulations) in force in the place of installation. In detail, natural gas plants must show features complying with the law provisions or regulations in force in the place of installation or at least complying with the standards EN 12186 or EN 12279. The installation in compliance with such standards minimizes the risk of fire and the formation of potentially hazardous atmospheres. The equipment is not provided with internal pressure limitation devices; therefore, it must be installed making sure that the operating pressure of the installation in which it is installed does not exceed the value of the allowable maximum pressure (PS). The user shall therefore, when he/she deems it necessary, provide for the installation on the assembly of suitable pressure limitation systems; Moreover, the user shall equip the plant with suitable relief or drain systems in order to be able to discharge the pressure and the fluid contained in the plant before proceeding with any inspection and maintenance activity. Should the installation of the equipment require the installation on site of compression fittings, these latter have to be installed following the instructions provided by the manufacturer of the fittings. The selection of the fittings must be compatible with the use specified for the equipment and with the plant specifications, when foreseen.

The pressure regulator DIVAL 500 is a pressure regulator for previously cleaned gaseous fluids, suitable for low, medium and high pressure. DIVAL 500 is a normally open regulator and, therefore, it opens in case of:

- breakage of the main membrane;

- lack of regulated pressure signal. The main features of this regulator are:

  • Design pressure PS: up to 20 bar
  • Operating temperature: -20 °C ÷ + 60 °C;
  • Ambient temperature: -20 °C ÷ + 60 °C;
  • Range of the inlet pressure bpu: 0.2 to 20 bar
  • Possible regulation range Wd:

13 ÷ 100 mbar for BP head;

100 ÷ 300 mbar for MP head;

300 ÷ 2500 mbar for TR head;

  • Minimum differential pressure: 0.1 bar;
  • Accuracy class AC: up to 5 (depending on the outlet pressure range).
  • Range of the lockup pressure SG: up to 10 (depending on the outlet pressure range).
