ZM/DN200-BIO butterfly valve for biogas, 230V actuator

Biogas butterfly valve – reliable gas shut-off

The ZM/DN200-BIO butterfly valve is a key component of gas installations, designed for the safe and efficient shut-off of biogas supply. The construction based on a flangeless butterfly valve combined with a 230V electric actuator ensures quick and reliable operation, minimizing the risk of explosion in industrial facilities. This is particularly important in automatic gas shut-off systems (ASO), where operational reliability is critical.

Construction and application

The ZM/DN200-BIO valve finds application in large-capacity gas boilers and industrial gas installations. Its flangeless design simplifies installation, and the ability to install it in any direction of gas flow increases installation flexibility. Thanks to a special internal sealing ring, there is no need to use external flange gaskets, which translates to easy installation and no additional operating costs. It is worth emphasizing that this valve is dedicated to biogas, which confirms its resistance to the aggressive components of this fuel.

Key features and benefits

• Fast and effective shut-off: The 230V electric drive guarantees valve closure in less than 12 seconds, which is crucial in emergency situations.
• Universal mounting: The ability to install in any direction and position facilitates integration with existing infrastructure.
• Lightweight construction: Compared to traditional ball valves, the valve is much lighter (e.g., DN150 weighs only 15 kg), making it easier to transport and install, especially at heights.
• Minimal pressure drop: The valve design ensures a negligible pressure drop, which translates to energy efficiency of the installation.
• No maintenance required: The solid construction and high-quality materials ensure years of trouble-free operation without the need for regular inspections and maintenance.
• Safety: Designed for biogas, ensures safe operation of the installation with this fuel.
• Standard equipment: The set includes an electric actuator, a manual closing wheel, and a terminal box with cable glands – everything ready for installation.
• Available pressure ranges: The valve standardly operates at a pressure of 1 MPa (10 bar), but versions with other parameters (0.3 MPa, 0.6 MPa or 1.6 MPa) are available on request.

The ZM/DN200-BIO valve is a solid and reliable solution for professionals and end-users looking for a safe and efficient way to shut off the biogas supply in their installations. Its dimensions (380 x 680 x 220 mm) allow for easy adaptation to existing infrastructure.
