Automatic shut-off valve for fire protection systems Danfoss EV220B DN100 4 inch, without PZH certificate 016D6100

Automatic shut-off valve for fire protection systems – reliable protection and fast response

This Danfoss EV220B DN100 (4 inch) automatic shut-off valve is a key element of fire protection systems, providing quick and effective cut-off of medium flow in the event of a hazard. The valve's construction, made of durable cast iron, guarantees long-lasting and trouble-free operation even in difficult conditions. The valve is designed to work with water and glycol in the temperature range of -25°C to +90°C.

The EV220B valve is characterized by a high flow rate – the Kvs value is 130, which allows for effective protection of large areas. The minimum differential pressure of 0.25 bar ensures reliable opening and closing, and the maximum working pressure of 10 bar guarantees the safety of the installation. Thanks to the use of an EPDM gasket, the valve is resistant to many chemicals and ensures a tight connection.

The valve is supplied as a separate body, which facilitates installation and integration with existing systems. The set includes flange gaskets and mounting screws and nuts. Please note that flange kits must be purchased separately. The valve has a non-energized NC (normally closed) position, which means that it is closed at rest and opens only after receiving an electrical signal. The maximum medium viscosity with which the valve can operate is 50 cSt.

• Durable construction: The cast iron body provides resistance to mechanical damage and corrosion.
• High flow rate: The Kvs value of 130 enables effective protection of large areas.
• Wide temperature range: Operation in the range of -25°C to +90°C allows for use in various environmental conditions.
