Full-bore ball valve for gas with steel lever (N-N version) 4TECH DN15 nickel-plated 3402600

4TECH ball valve is a component of a gas installation that combines innovative solutions and high-quality workmanship. Designed for full-bore application, with a solid steel lever, it provides convenient and safe operation. Made of brass and nickel-plated, it guarantees corrosion resistance and durability.

Safety and reliability first

A key feature of the 4TECH series valves is the patented sealing system. In addition to standard Teflon gaskets, additional copper rings are used. In the event of a fire, when Teflon and rubber gaskets melt, the copper rings, due to thermal expansion, seal the valve tightly. This unique solution minimizes the risk of gas leakage and potential explosion. The valve meets the requirements of the European standard EN 331:1998/A1:2010 for gas valves, which confirms its safety and reliability – it is marked with the CE and HTV (High Temperature Valve) symbols.

Design and application

The valve is characterized by a massive body with increased wall thickness, which translates into greater resistance to cracking and mechanical damage. The ergonomic shape of the lever ensures comfortable operation even in difficult conditions. The valve is intended for installation in gas installations with a maximum working pressure of 20 bar (PN20). Its versatility makes it suitable for both domestic and industrial installations.

Key advantages

• Innovative sealing system: a combination of Teflon and copper gaskets provides exceptional tightness and safety.
• Self-sealing in case of fire: copper rings activate at high temperature, sealing the valve and minimizing the risk of gas leakage.
• Durable construction: thicker body increases resistance to cracking and mechanical damage.
• Ergonomic lever: ensures comfortable valve operation.
• Compliance with standards: meets the requirements of EN 331:1998/A1:2010 and has CE and HTV markings.
• Nickel-plated finish: provides corrosion resistance and aesthetic appearance.
