Butterfly valve ZM/DN200 butterfly valve, 230V actuator

Butterfly valve for gas safety systems

The ZM/DN200 valve is a reliable shut-off valve designed for quick and effective gas shut-off in industrial installations and gas boiler rooms. Used in Automatic Shut-off Systems (ASO), it minimizes the risk of natural gas, biogas, hydrogen or ammonia explosions. Its design allows for universal mounting and flow direction, and the collarless construction simplifies installation.

Key features for professionals:

• Fast action: 230V~ electric drive ensures valve closure in less than 12 seconds.
• Versatility: Can be installed in any position and flow direction.
• Easy installation: Collarless design simplifies installation and reduces working time.
• Low weight: Compared to traditional ball valves, the ZM/DN200 butterfly valve is much lighter, making it easier to transport and install – for example, the DN150 model weighs only 15 kg.
• Minimal pressure drop: A special sealing ring eliminates the need for external flange seals, minimizing pressure loss and gas flow disturbances.

Application and benefits for the end user:

The ZM/DN200 valve is used in high-power gas boiler rooms and industrial gas installations. Its robust construction and maintenance-free operation guarantee years of trouble-free operation, ensuring safety and peace of mind. Thanks to the possibility of selecting seals for aggressive media, the valve can be used in various industrial environments. Standard equipment includes an electric actuator, a manual shut-off knob and a terminal box with cable glands – all ready for connection and commissioning.

Technical parameters and construction:

The valve has a diameter of DN200 and a nominal pressure of 1.0 MPa (10 bar). The flanged connection ensures tightness and easy integration with existing infrastructure. The possibility of ordering versions with different working pressures (0.3 MPa, 0.6 MPa or 1.6 MPa) allows the valve to be adapted to specific installation requirements. The dimensions of the butterfly valve are 380 x 680 x 220 mm. The design allows for both electrical control (230V~) and manual operation using a knob. The valve complies with applicable safety standards for gas appliances.
