◆ The two-position three-way solenoid valve is the main starter component of the system. The gas is delivered to the pilot valve of the deluge system through the solenoid valve to keep the system closed. When a fire occurs, the central control system opens the solenoid valve remotely, the gas is released, and the deluge system opens immediately; when it needs to be closed, the central control system restores to the original state, and the system can only be closed by pressing the manual reset button of the solenoid valve after it is confirmed on the site that the fire alarm has been relieved. The solenoid valve has passed the SIL3 Safety Integrity Level certification.

Installation and maintenance
The solenoid valve is the most important component in the deluge system. It should be installed and wired by qualified and trained personnel. The coils should be connected in accordance with applicable standards such as IEC or ATEX specifications. It is necessary to make sure that the voltage and frequency are consistent with what is marked on the enclosure label.
Warning：only an authorized electrician should be allowed wire this product. When assembling the product, please use suitable tools to support the wire box of the housing. When tightening the fittings into the wire box, be careful that the maximum torque should not exceed 20Nm.
Maintenance：it is necessary to regularly check whether the solenoid valve is operating normally. When being used, the solenoid valve should be tested and maintained in accordance with the specific IOM (Installation Operation and Maintenance) manual of the Bermad valve. It is recommended to check the correct wiring and sealing of the solenoid valve every month. The solenoid valve must be tested once a year. The maximum working pressure must be applied to the system to simulate extreme environments. If a device fails, it should be replaced.
