Automatic shut-off valve for fire protection systems – reliability and high flow rate

This solenoid valve, designed for automatic flow shut-off in fire protection systems, combines a robust construction with high performance. It is a key component of fire protection systems, ensuring a quick and effective response in the event of a hazard. The valve is normally open, meaning it is open under normal conditions and closes only upon receiving an electrical signal – a typical solution in safety systems. It operates at 230V.

The valve is characterized by a high flow coefficient Kv of 78 m³/h, which translates to very high flow rate and low flow resistance. This is important because it allows for quick delivery of the medium (fresh water or glycol) to the fire location. This value is higher than many competing solutions, ensuring more efficient system operation. The 2/2-way design provides simple and reliable operation.

The valve is designed to work with media such as fresh water and glycol at temperatures from -25°C to +90°C. The maximum working and test pressure is 16/25 bar, and the EPDM seals are resistant to the action of these media up to a temperature of 90°C. The minimum opening pressure difference is 0 bar, and the maximum is 16/25 bar. The nominal diameter of the valve is DN65, and the connection type is flanged. It has a PZH certificate confirming its safety and compliance with sanitary requirements.

The valve is equipped with a coil and has a PZH certificate, confirming its safety and compliance with sanitary requirements. It is designed to operate at a maximum working pressure of 16/25 bar. The simple construction of the valve guarantees certainty and reliability of operation for a long time. EPDM seals provide resistance to water and glycol over a wide temperature range. Flanged mounting facilitates integration with existing installations. The valve will work in both new installations and during the modernization of existing fire protection systems.
