Notes
Product Overview
VE4040A1243T is a DN40 normally closed solenoid gas valve used as a safety shut-off valve in high-capacity commercial and industrial burner systems.
It is typically installed as the main gas shut-off valve where large gas volumes must be safely controlled.
The DN40 size makes it suitable for larger boilers, industrial furnaces, and heating systems that require both fast response and robust mechanical construction.
Key Features
