Biogas check valve MAG-3/DN65-BIO biogas check valve, Ex, flange set DN65

The MAG-3/DN65 check valve 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 gas installations in residential and public buildings, as well as in external reduction and measurement points. Versions marked as BIO are dedicated to working with biogas from landfills or sewage treatment plants.

The valve's construction ensures reliable operation under various conditions – it does not require power in the open or closed position, which translates to energy saving. It operates bistably, closing with an electric pulse of 12V (lasting less than a second) or manually using a button on the housing. Immunity to power failure guarantees continuous operation even
