Frequently asked questions

What is the Staflux Mini used for?

The Staflux Mini is a compact, direct operated regulator used on CNG trailers, high pressure transmission and medium pressure distribution. It takes 5 to 250 bar inlet and controls 4 to 75 bar outlet with a 1 bar minimum differential. It is classified fail close under EN 334, has a built-in filter and does not require gas pre-heating.

Which connections and gases does the Staflux Mini support?

Its flyer gives a 1 inch body with Class 1500 RF flanges per ASME B16.5 or threaded NPT ends. It is meant for previously filtered, non-corrosive gases, and the flyer states compatibility with biomethane and 20% hydrogen blending. For a fail open regulator with the same 250 bar rating, see the Staflux 187.

Do you supply the Staflux Mini in Saudi Arabia and the GCC?

Pietro Fiorentini Saudi Industry in Al Khobar supplies and supports the Staflux Mini for projects in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Contact us with your operating conditions and connection type for a quotation.
