Product Overview
The DUNGS MVD 515/5 is a normally closed, single-stage automatic shut-off gas solenoid valve engineered for the safe control of combustible gases in industrial combustion systems. Manufactured by DUNGS (Karl Dungs GmbH & Co. KG), a global leader in gas safety and control technology, the MVD series combines a compact valve body with a Class A solenoid actuator for fast, reliable open/close operation. The valve functions as a safety shut-off device in gas trains, opening when energized to permit gas flow and closing instantly upon power interruption, thereby preventing uncontrolled gas release. Its pressure-bearing design and proven sealing technology make it a core component in modulating and staged burner control architectures across process heating, boiler, and furnace applications.
