MV300-350A — Magnetic solenoid shut-off valve for water supply

Magnetic solenoid valve MV300-350A with nominal diameter DN350 and flow coefficient Kvs 2000 is a highly efficient solution for reliable shut-off control of drinking water flow. This model is ideal for use in industrial and commercial systems where precise and stable water supply regulation is required. The compact flange body ensures ease of installation even in confined spaces such as ventilation ducts, engineering shafts, and pipeline nodes.

Operating principle and safety

MV300-350A belongs to the class of pilot (controlled) valves with an integrated magnetic solenoid. A key feature of this model is its behavior when power is off: the valve automatically closes, ensuring system safety and preventing unwanted water flow. This mode of operation is especially important for systems where maintaining a certain operating state under any conditions is required.

Main areas of application:

• Engineering systems for drinking water supply (household and public facilities).
• Industrial and commercial installations requiring precise and stable flow shut-off.
• Installation in narrow spaces (pipelines, air ducts, distribution collectors).

Key advantages:

• Compactness: Convenient for installation in tight conditions.
• Solenoid control: Integrated electromagnetic mechanism for operation in control systems.
• Safety when power is off: The valve automatically closes when power is lost.
• Reliability in operation: Designed to operate within the required temperature range.
• Compliance with standards: Has approvals from DVGW and WRAS, confirming suitability for use in water supply systems.
