Brass Threaded Ball Valves for Natural Gas

Detailed Information on Brass Threaded Ball Valves for Natural Gas

Brass threaded ball valves for natural gas are manufactured to meet the safety requirements of the EN 331 standard. The yellow-coated handle provides easy identification for gas line equipment, while the blow-out proof stem structure ensures safe operation even under high pressure. Full sealing is achieved with PTFE or specialized gas gaskets.

Key Advantages

• • Full compliance with EN 331 standard.
• • Yellow-coated handle – international marking for natural gas.
• • Blow-out proof stem (secured against stem ejection).
• • High sealing in gas lines with PTFE gaskets.
• • BSP threaded connections for easy installation.
• • Low pressure loss with full-bore sphere.
• • Compact design suitable for confined spaces.
• • Corrosion-resistant nickel plating options.
