Dungs MBC-700-SE-S82 Gas Solenoid Valve Detailed Introduction
I. Product Overview
The Dungs MBC-700-SE-S82 is a high-performance gas solenoid valve produced by Dungs, Germany. This product integrates a filter, valve, and servo pressure regulator into a compact unit, making it suitable for precise control of gas flow and pressure in various gas equipment such as burners, boilers, and burner nozzles.
II. Product Features
High Integration: Multiple functional components are integrated into one, reducing system complexity and installation space.
High-precision Regulation: The servo pressure regulator can precisely adjust the output pressure, ensuring extremely stable output pressure to meet high-precision control requirements.
High Flow Capacity: Even with a small pressure differential, it can achieve high flow output, satisfying the demands of high-load equipment.
Safe and Reliable: It complies with multiple international standards and safety norms, ensuring safety and reliability during use.
Modular Structure: It is convenient for maintenance and upgrades, and can be equipped with accessories such as valve detection systems, pressure monitors, and pressure limiters according to actual needs.
III. Working Principle
The working principle of the Dungs MBC-700-SE-S82 solenoid valve is as follows:
Closed State: When valves V1 and V2 are closed, chamber a is under input pressure. At this time, the gas flow is blocked.
Opening Process:
When the automatic gas combustion control device sends an opening signal, the solenoid coil is energized.
The electromagnetic force acts to open valves V1 and V2.
The gas flows through chambers a and b into the burner.
Pressure Regulation:
The servo pressure regulator adjusts according to the preset output pressure.
By adjusting the spring and servo diaphragm, the output pressure remains stable.
Closing Process:
When the solenoid coil is de-energized, the spring force quickly closes valves V1 and V2.
The gas flow is cut off, ensuring equipment safety.
