Automatic shut-off valve for fire protection system Danfoss EV220B DN80 3 inch, without PZH certificate 016D6080

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

This Danfoss EV220B DN80 (3 inch) automatic shut-off valve is a key component of fire protection systems, providing quick and effective cut-off of medium flow in the event of a hazard. The valve is designed to work with water and glycol in the temperature range of -25°C to +90°C, making it a universal solution for various installations. The cast iron body construction guarantees durability and corrosion resistance, and the EPDM seal ensures tightness.

The EV220B valve is characterized by a high flow rate – Kvs 75 – which minimizes pressure loss in the installation. The minimum differential pressure required to open the valve is 0.25 bar, and the maximum working pressure is 10 bar, ensuring its proper operation under typical working conditions. The maximum medium viscosity with which the valve can operate is 50 cSt.

Construction and application

The valve is supplied as a separate body, which facilitates assembly and servicing. The set also includes flange gaskets and mounting screws and nuts. Thanks to the DN80 (3 inch) flanged connection, the valve is easy to integrate with existing installations. It is an ideal solution for both new installations and modernization of existing fire protection systems. The valve operates in a normally closed (NC) system, which means it is normally closed and only opens after receiving a control signal.

Key features and benefits
