Product Overview

The Tartarini BM5 Series is a sleeve closing axial flow slam-shut valve that shuts the gas flow when the pressure rises above or falls below the set levels. It is installed as an independent safety device upstream of the regulator in regulating stations and gas distribution piping. The sleeve design opens against balanced pressure, so no external by-pass line is needed to re-open the valve after a trip.

Key Features

• Sleeve closing axial flow design, DN 25 to DN 150, PN16, PN25 or CL150-CL600
• Maximum inlet pressure 100 bar / 1450 psig, operated by line gas only
• Overpressure trip 0.03-80 bar and underpressure trip 0.01-80 bar
• Accuracy up to +/-1% with response time under one second
• Protected seal pad, emergency push-button release and manual reset shaft

Typical Applications

Natural gas, air, propane, butane, LPG, city gas, nitrogen, carbon dioxide and hydrogen regulating or distribution installations, including district stations, industrial plants and burner supply lines.

Selection Guide

State the pipe size (DN 25 to DN 150), flange standard (PN 16, PN 25 or CL150-CL600), the required overpressure and underpressure trip values, and the ambient temperature. Low temperature construction and hydrogen validated configurations are available on request.
