Full-bore ball valve for gas with steel lever (N-N version) 4TECH DN20 nickel-plated 3403600

Gas ball valve – safety and reliability of the installation

This 4TECH DN20 full-bore nickel-plated ball valve combines solid construction with innovative solutions to ensure safety in gas installations. Designed for both professional use and demanding end-users, it offers reliable gas shut-off. The valve's design is intended for easy installation and long-term operation.

The valve is distinguished primarily by the use of a patented sealing system. In addition to standard Teflon gaskets, it has additional copper rings. In the event of a fire, when the Teflon gaskets melt, the copper rings expand under the influence of temperature, sealing the valve and minimizing the risk of gas leakage. This is a key solution that increases the safety of the entire system. The valve meets the requirements of European standard EN 331:1998/A1:2010, which confirms its high quality and compliance with applicable standards. The presence of the CE marking and the HTV (High Temperature Valve) mark on the body indicates resistance to high temperatures.

• Innovative sealing system: A combination of Teflon and copper gaskets ensures reliable operation even in extreme conditions.
• Self-sealing in case of fire: Copper rings react to high temperature, automatically sealing the valve and preventing gas leaks.
• Durable construction: Thicker valve body increases its resistance to cracking and mechanical damage.
• Ergonomic lever: Facilitates operation and ensures user comfort.
• Compliance with standards: Meets the requirements of EN 331:1998/A1:2010, guaranteeing safety and reliability.
• Ball material: Made of brass – a material resistant to corrosion and ensuring long-term tightness.

The 4TECH valve is an investment in safety and peace of mind. Its solid construction and innovative solutions make it an ideal choice for both professional installers and users who care about safety in their homes. Thanks to precise workmanship and the materials used, the valve ensures long-lasting and trouble-free operation in various installation conditions.
