The Suntec M2N / M3N Gas Valve is a compact combined gas valve unit designed for 1-stage gas burner applications. It integrates two safety solenoid valves in a single body, ensuring reliable and secure gas flow control.

At rest, both solenoid valves remain closed, preventing gas flow. When energized, both valves open simultaneously, allowing gas to pass through the system safely and efficiently.

The valve is built with a high-strength aluminum body and offers customizable configurations, including different flange sizes, pressure taps, and optional pressure switch integration.

It is compatible with natural gas, LPG, and hydrogen blend gases, making it suitable for modern industrial burner systems and evolving fuel requirements.

Optional slow opening functionality ensures smoother ignition and compliance with burner safety standards such as EN 676.

Technical Description

The Suntec M2N / M3N Gas Valve operates using two integrated solenoid valves. When the system is not powered, both valves remain closed, blocking gas flow.

When electrical power is applied, both solenoid coils are energized, causing the valves to open and allow gas to flow through the valve body to the burner.

The valve ensures rapid shut-off (less than 0.2 seconds) when power is removed, preventing gas leakage and improving system safety.

An optional hydraulic damper system allows slow opening of the valve, reducing pressure shock and ensuring smoother burner ignition.
