Pietro Fiorentini Gas Regulator

Gas Pressure Regulators Mod. FE
Gas Pressure Regulator FE industrial
 

FE is a double-stage self-operated pressure regulator for civil and industrial applications and it is suitable for use with gaseous fluids such as natural gas, LPG and non-corrosive gases.

They can be installed in any position and in environments or spaces protected against weather. The discharge of the internal relief valve can be conveyed outside in case of installation in closed rooms or underground installations. The regulators are manufactured according to the UNI 8827 standard and the Italian Ministerial Decree dated 16 Apr. 2008; for the classification of the functional performance, reference shall be made to the EN 16129 and EN 334 standards.

Direct-Acting Gas Pressure Regulator Dival 500
Pietro Fiorentini Gas Pressure Regulator Dival 500
 

The DIVAL 500 series of spring loaded, diaphragm controlled balanced plug gas regulators are suitable for low, medium and high pressure. Divals and shut-off device series regulators are supplied with internal sensing lines. Both the regulator and the shut-off device are preset for optional connection to an external sensing line by the customer. They are widely used in both civil and industrial installations using Natural Gas, LPG and other non-corrosive gases.
  
The special regulator design combined with a balanced plug result in:

  • High flow rate coefficient,
  • High accuracy, even at maximum flow rates,
  • Reduced lock-up pressure zone and lock-up pressure,
  • Reduced response times,
  • No internal leakage at zero flow rate,
  • Fail open type,
  • Regular l maintenance without disassembling the body from the pipework,
  • Ability to retrofit the slam-shut OPSO/UPSO, (only LA model) without modifying the existing pipe.

Direct-Acting Gas Pressure Regulator Dival 600
Pietro Fiorentini Gas Pressure Regulator Dival 600
 

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.

Pilot-Operated Gas Pressure Regulator Reval 182
Governor industrial gas regulator
 

The Reval 182 is a pilot-controlled pressure regulator for medium and low pressure.
  
The Reval 182 is a 'fail close' regulator, i.e. it closes if:

  • The main diaphragm fails
  • The pilot diaphragm's fail
  • There is no feed to the pilot loop

These regulators are suitable for use with pre-filtered, non-corrosive gases.
