Tartarini Type BM9 Slam Shut Valve

Tartarini Type BM9 Slam Shut Valve

Tartarini™ Type BM9 slam-shut valve is an axial flow type, automatic shut-off device suitable for installation as safety device in regulating, distribution and transmission stations of suitably filtered natural gas.

The slam-shut valve has the task to quickly shut off the gas flow when the pressure in control point(s) reaches a fixed set value.

Type BM9 is designed to be used with fuel gases of 1st and 2nd family according to EN 437, and with other non-aggressive and non-fuel gases. For any other gases, other than natural gas, please contact us.
