Biogas Check Valve – Safety and Reliability in Gas Installations

The MAG-3/DN32 check valve is an actuator of the Active Gas Installation Safety System of the GX type, designed to automatically shut off the gas supply in the event of an explosion hazard. Particularly dedicated to working with biogas from landfill sites or wastewater treatment plants, but it will also work in standard gas installations. Its construction ensures reliable operation and ease of use, which will be appreciated by both installers and end users.

Construction and Application

The MAG-3/DN32 is characterized by a full-bore design and is intended for mounting in systems protecting gas installations, including gas boiler rooms, public buildings and external gas reduction and metering stations (up to a working pressure of 0.5 MPa). It also finds application in cogeneration systems in wastewater treatment plants and landfills. Thanks to the possibility of working in potentially explosive atmospheres (compliance with the ATEX Directive), it is an ideal solution for demanding industrial applications.

The valve opens manually, while closing occurs via a short electrical impulse (12V=) or using a button on the housing. This feature ensures a quick response in emergency situations and minimizes the risk of damage. Importantly, the valve does not require power to maintain the open or closed position – it is energy-saving and insensitive to power supply failures. This eliminates the risk of uncontrolled valve operation due to power supply problems.

Advantages and Benefits

• Safety: Automatic shut-off of gas supply in the event of an explosion hazard.
• Versatility: Designed to work with biogas and natural gas/propane-butane.
• Energy Saving: Does not require constant power – an electrical impulse is only needed to close the valve.
• Reliability: Resistant to interference and voltage drops – ensures stable system operation.
• Ease of Use: Manual opening and electrical/manual closing make operation easier.
• Durability: Solid construction guarantees long device life.
• Compliance with Standards: Can be used in potentially explosive atmospheres in accordance with the ATEX Directive.
• Completeness: The valve is supplied with an opening key, two steel counter flanges, gaskets and a set of screws and nuts – ready for installation.

The MAG-3/DN32 check valve is an investment in safety and peace of mind, for both professional installers and end users. Its reliability, ease of use and compliance with standards make it an ideal choice for a variety of applications in gas installations.
