Full-bore ball valve for gas with steel lever (N-N version) 4TECH DN25 nickel-plated 3404600

Gas ball valve – safety and durability in one

This 4TECH DN25 full-bore nickel-plated ball valve with a steel lever (N-N version) is a reliable solution for gas installations, combining innovative technologies and a solid construction. Designed for both professional use and demanding end customers, it provides safe and efficient gas shut-off.

Construction and application

The valve is designed with maximum safety in mind. Its key feature is a patented sealing system that utilizes both Teflon seals and copper rings. In the event of a fire, when the Teflon seals melt, the copper rings expand thermally, sealing the valve and minimizing the risk of gas leakage. This means it meets the requirements of the European standard EN 331:1998/A1:2010 for gas valves, confirmed by the CE marking and the HTV (High Temperature Valve) symbol on the body.

The valve is used in domestic and industrial gas installations where high reliability and resistance to extreme temperatures are required. It is ideal for shutting off the gas supply to heating appliances, gas stoves or underfloor heating installations.

Advantages and benefits
