I. Product Overview
The Dungs DMV-DLE-520/11 gas solenoid valve is produced by German company DUNGS, utilizing advanced dual solenoid valve technology that integrates two solenoid valves into a compact housing. This product complies with DIN EN 161 Class A, Category 2 standards and is an automatic shut-off valve specifically designed for gas control, ensuring the safety and reliability of gas systems.
II. Product Features
Dual Solenoid Valve Technology:
Integrated Design: The two solenoid valves are compactly combined, reducing installation space and enhancing system integration.
Independent Control: The two solenoid valves can be independently controlled, increasing system flexibility and reliability.
High Performance:
High Flow Rate: Employing dual disk valve technology, it provides a high flow rate to meet the demands of various gas systems.
Rapid Response: Features rapid closing and opening functions (fast-opening model DMV-D/11 or slow-opening model DMV-DLE/11) with a quick boost function for starting gas flow, enhancing system response speed.
Adjustability:
Main Flow Adjustable: The main flow regulation device on the valve allows manual limitation of gas flow to meet different flow requirements.
Opening Time Adjustable: For the slow-opening model (DMV-DLE/11), the quick-opening stroke for starting gas flow can be adjusted to suit different application scenarios.
Safety and Reliability:
Compliance with Standards: Meets DIN EN 161 Class A, Category 2 requirements, ensuring product safety and reliability.
Material Selection: The materials in contact with gas are aluminum and steel, containing no non-ferrous metals, making it suitable for gas environments containing up to 0.1% hydrogen sulfide (H₂S) by volume.
Easy Installation and Maintenance:
DC Solenoid Coil: Provides stable electromagnetic force, ensuring reliable opening and closing of the valve.
Removable Terminal Contacts: Facilitates installation and maintenance, reducing operating costs.
Multiple Connection Options: Offers threaded flange connections for easy connection to gas pipelines.
