1、Brand and Manufacturer
Brand: Dungs
Manufacturer: Dungs is a manufacturer with an excellent reputation in the field of gas control, specializing in providing high-quality gas control valves and accessories widely used in industrial burners, boilers, water heaters, and other gas-fired equipment.
2、Product Overview
Type: Gas Solenoid Valve
Model: DMV-D-503/11 (222326)
Purpose: This solenoid valve is mainly used in gas control systems to precisely control the supply and shut-off of gas, ensuring the safe and efficient operation of gas-fired equipment. It is suitable for various gas-fired devices such as gas burners, boilers, and gas water heaters.
3、Technical Features
Dual Solenoid Valve Design: The DMV-D-503/11 consists of two solenoid valves compactly combined, with two A valves housed in one shell, achieving dual valve control and enhancing system reliability and safety.
High Flow Rate: Utilizing dual disc valve technology, it provides a high flow rate to meet the control needs of high-flow gas equipment.
Rapid Response: The solenoid valve has a fast response time, enabling quick opening or closing of the gas passage to ensure immediate control of gas-fired equipment.
Adjustable Main Flow: The main flow can be manually limited through the main flow adjustment device on the valve, satisfying control requirements under different operating conditions.
DC Solenoid Coil: Adopting a DC solenoid coil, it operates stably and reliably with a long service life.
Compact Size and Light Weight: The compact design makes the solenoid valve small in size and light in weight, facilitating installation and integration into various gas control systems.
4、Working Principle
When the coil is energized, it generates a magnetic field that attracts the valve core, opening the gas passage. When the power is cut off, the magnetic field disappears, and the valve core resets under the action of a spring, closing the gas passage. By controlling the on/off state of the coil, precise control of the gas passage is achieved.
5、Applicable Media
This solenoid valve is primarily suitable for non-corrosive gas media such as coal gas, natural gas, and liquefied petroleum gas.
6、Performance Parameters
Working Pressure: Up to 0.5 bar
Opening Time: Less than 1 second (specific values may vary depending on the model and operating conditions)
Closing Time: Less than 1 second
Main Flow Adjustment: Can be manually adjusted through the adjustment device on the valve
Electrical Connection: Complies with DIN EN 175 301-803 plug connection
Voltage/Frequency: AC 50-60Hz, 220-230V (other voltages and frequencies are available)
Ambient Temperature: -15°C to +60°C
Materials in Contact with Gas: The shell is made of aluminum and steel, containing no non-ferrous metals; the valve seat seal is made of NBR-based material, suitable for G260/1 gas
7、Safety Features
Explosion-proof Design: Suitable for potentially explosive environments, ensuring the safe operation of the equipment.
Filtration Device: A screen filter is installed to protect the gas passage from impurities. It is recommended to install a gas filter at the frontend to further protect the entire gas passage.
Pressure Monitoring: Can be equipped with a pressure monitor to real-time monitor gas pressure and ensure the safe operation of the system.
8、Installation and Use
Installation:
Follow relevant installation codes and standards to ensure a secure and tightly sealed connection between the solenoid valve and the gas pipeline.
The installation location should be convenient for maintenance and inspection, and should avoid mechanical shock and vibration.
The electrical connection should comply with safety standards to ensure correct wiring.
Use:
Regularly check the working status of the solenoid valve during use to ensure its normal operation.
If any abnormalities or faults are found in the solenoid valve, shut down the equipment for maintenance promptly to avoid safety accidents.
Comply with relevant safety operating procedures to avoid safety accidents caused by improper operation.
