ZM/DN125-BIO butterfly valve for biogas, 230V actuator

Biogas butterfly valve – reliable gas shut-off

The ZM/DN125-BIO butterfly valve is a key component of gas installations, designed for safe and effective shut-off of biogas supply. The construction based on a flangeless butterfly valve combined with a 230V electric actuator ensures a fast response and reliable operation. This valve is used in high-power gas boilers and industrial gas installations, where safety is a priority.

Construction and practical application

The ZM/DN125-BIO butterfly valve has been designed for easy installation and a wide range of applications. The flangeless design simplifies installation, and the ability to route gas flow in any direction and installation method increases flexibility during installation design. Thanks to a special internal sealing ring, there is no need to use external flange seals, which translates into saving time and costs associated with maintenance. Importantly, this valve can be part of an Automatic Shut-off System (ASO), providing an additional level of safety in the event of a failure or gas leak.

Key features and benefits

• Fast action: The 230V electric actuator guarantees a lightning-fast shut-off of the gas supply in emergency situations – the closing time is less than 12 seconds.
• Lightweight construction: Compared to traditional ball valves, the butterfly valve is much lighter (e.g., DN150 weighs only 15 kg), which facilitates transport and installation.
• Minimal pressure drop: The valve design ensures a negligible pressure drop, which translates into efficient installation operation and minimizes energy losses.
• Versatility: The ability to select seals for aggressive media expands the range of valve applications.
• Maintenance-free: No maintenance requirement ensures years of trouble-free operation.
• Durability: The maximum working pressure is 1 MPa (10 bar) in the standard version, and versions with higher pressure (0.3 MPa, 0.6 MPa or 1.6 MPa) are available on request.
• Ready to work with biogas: The special design and materials ensure compatibility with biogas.
• Dimensions: 280 x 550 x 160 mm – compact dimensions facilitate integration with existing infrastructure.

The ZM/DN125-BIO butterfly valve is characterized by a valve diameter of DN125, a nominal pressure of 1.0 MPa and a flanged connection. The power supply of the electric actuator is 230V~, and the closing time is less than 12 seconds.

The ZM/DN125-BIO butterfly valve is a solid and reliable solution for professionals and end-users looking for a safe and effective way to shut off the biogas supply in their installations.
