Brand: Pietro Fiorentini S.p.A.
Request Information
When requesting information, please download the Fillable PDF to provide details about your regulator use case. Instructions for completing the form are found in the footer of the document. Once completed, please upload the document with the Request for Information.
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
Features
  • Top Entry Design
  • Direct, Spring Operated
  • Normally “Fail Open”
  • Medium to High Pressure Outlet
  • Body Materials: Ductile Iron/Steel
  • Connections: 150 RF, threaded
  • Ratings: ANSI 150
  • Maximum Inlet Pressure: 290 PSIG for MP/TR and 145 PSIG with BP head
  • Outlet Pressure Range: 4” w.c. to 30 PSIG
  • Internal or External Control
  • Optional Integral Slam Shut Valve
