Dungs DMV Design
Gas electromagnetic valves are made of materials resistant to wear and corrosion. Aluminum and steel were used in the manufacture of the housing and structural elements, and NBR rubber for gaskets, designed for low-temperature operation.
The housing is prepared for connecting other automatic devices, such as a minimum, maximum pressure sensor, a leak test unit and other equipment. Permissible operating temperatures: -15...+60 °C.
A filter made of stainless steel mesh is installed at the inlet of the electromagnetic valve, retaining coarse particles and impurities larger than 1 mm. Installation of the main gas filter is mandatory.
Application
Dungs DMV gas electromagnetic valves can be integrated into burners of a wide range of manufacturers. They are used in large industrial heating systems, heat generating equipment, and for the modernization of old boiler houses. They are installed to replace two separate electromagnetic valves.
