Automatic shut-off valve for fire protection systems Danfoss EV220B DN80 3 inch, CNBOP 016D3331

Automatic shut-off valve for fire protection systems – reliable protection and certified safety

This Danfoss EV220B DN80 (3 inch) automatic shut-off valve is a key element of fire protection systems, designed for reliable operation and compliance with stringent safety standards. The valve, made of cast iron, is intended for operation in demanding conditions where fast response and high throughput are essential. It has CNBOP certification, which guarantees its compliance with Polish regulations regarding fire protection installations.

Design and practical application

The EV220B valve is a 2/2-way servo-controlled solenoid valve, which means its operation is hydraulically assisted – this ensures quick and reliable opening and closing. The design minimizes the risk of hydraulic shock, and the built-in pilot system filter protects against damage caused by contaminants. The purpose of this valve is primarily to automatically cut off the medium supply in the event of a fire, protecting the installation and minimizing losses. Flanged connections DN80 (3 inches) facilitate installation in existing systems.

Key features and benefits

• CNBOP certificate: Confirms compliance with Polish standards for fire protection installations – peace of mind for designers and investors.
• High flow rate (Kvs = 75): Ensures rapid medium flow, which is crucial in fire protection systems.
• Durable cast iron construction: Guarantees long life and resistance to mechanical damage and corrosion.
• Servo control: Ensures quick and reliable valve operation, even with varying medium pressure.
• Built-in filter: Protects the pilot system from contamination, increasing operational reliability.
• NBR seal: Ensures tightness and compatibility with various media.
