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 element of fire protection systems, ensuring a rapid response in emergency situations. The valve operates at 230V and is normally closed – meaning it only opens after receiving an electrical signal. This provides additional safety by blocking flow in the event of a power failure.

The valve is made of high-quality materials, guaranteeing its long-lasting and trouble-free operation. EPDM seals are resistant to water at temperatures up to 90°C, as well as glycol, which expands the range of applications. It has a PZH certificate, confirming its compliance with sanitary and safety requirements.

Key features and applications

The 2/2-way valve with a DN100 flange mounting diameter is designed to work with water and glycol solutions in the temperature range from -25°C to +90°C. Its construction allows operation at a working pressure of 16/25 bar and a test pressure also of 16/25 bar. The high flow coefficient Kv of 204 m³/h ensures very high flow rate and low flow resistance – important in systems requiring rapid action. The minimum opening pressure difference is 0 bar, which facilitates valve start-up even at low pressure in the installation.

This valve finds application in:

• Automatic compressed air systems
• Fire protection systems using water or glycol
• Industrial installations requiring precise flow control of liquids
• Irrigation systems

Construction and advantages

The simple construction of this solenoid valve translates into its reliability and ease of servicing. A coil is included in the set, eliminating the need to purchase it separately. The high Kv coefficient distinguishes it from the competition, ensuring more efficient operation of the fire protection system. This allows installers to rely on reliable and effective object protection, and end-users – a sense of security. The valve has been designed to minimize pressure losses in the installation, making the system work more efficiently.
