Australian gas transmission and distribution businesses are facing increasing demand for reliable gas delivery from new and existing customers. The construction of new infrastructure and maintenance of existing requires quality components to ensure network reliability and safety.

The Aperflux 851 gas pilot regulator has an operating inlet pressure range of 1–85 bar with a maximum inlet pressure of up to 100 bar. The flanges are rated to class 150, 300 and 600, in accordance to ANSI 16.5 with available DN sizes 1, 2, 3, 4, 6, 8 and 10 inches. The working outlet pressure range is 0.8–74 bar with an accuracy class of 1.5 per cent. Flow rates of up to 40 terajoules per day (TJ/d) of gas can be achieved depending on size selection.

The gas regulator can be configured with a slam shut, monitor and silencer all in the one component for easy installation, and saves on additional pipe work and space normally required for separate components.

Pietro Fiorentini has recently launched the Aperflux 101, which offers excellent value for distribution and transmission businesses that require a high quality gas regulator but do not need the modular design.

The Aperflux 101 has an inlet pressure range of 1.8–85 bar with a maximum design inlet pressure of 85 bar. The outlet pressure working range is 0.8–74 bar, depending on the installed pilot. The available flanges are rated class 300 and 600 in accordance to ANSI 16.5 with available sizes of DN 2 and 3 inches. The accuracy class is 1.5 per cent and achieves flow rates of up to 7.2 TJ/d.

This new piloted regulator will have broad applications for distribution and transmission businesses for transmission receipt points, district and field regulator sets.
