Biogas check valve MAG-3/DN40-BIO biogas check valve, Ex, flange set DN40

Check valve MAG-3/DN40 is an actuator for an Active Gas Installation Safety System, designed to automatically shut off the gas supply and minimize the risk of explosion. Its use is particularly important in installations powered by biogas – both from landfills and sewage treatment plants. The valve design allows for manual opening and electrical closing (12V=), providing operational flexibility and a quick response in emergency situations.

This model, with a nominal diameter of 0.5 MPa and a DN40 flanged connection, is widely used in securing gas installations in boiler rooms, public buildings, and external reduction and measurement points. It is also indispensable in cogeneration systems using biogas. Its energy-saving design – no power required in the open or closed position –
