Stainless Steel 3-Piece Ball Valve NPT GW H-510

The three-piece medium-pressure ball valve is a robust and versatile solution engineered for the most demanding applications in the chemical, petrochemical, pharmaceutical, energy, and process engineering industries, ensuring reliable performance for both liquids and gases. Designed for pipeline installation, it offers a wide size range to guarantee optimal flow capacity, precise tightness with minimal internal leakage of just 0.1 Ncm³/min, and exceptional durability combined with low operating torque. Each unit undergoes rigorous nitrogen pressure testing and is certified according to ISO 15848-1:2006 (E), confirming its compliance with the highest international standards. Manufactured from premium AISI 316 stainless steel for the body, ball, and stem, with a lever made of AISI 304 steel and PVC, the valve ensures long-lasting resistance to corrosion and mechanical stress. The standard PTFE ball seal provides reliable performance, with optional advanced sealing materials such as modified PTFE, PTFE with stainless steel powder, UHMWPE, or PEEK available for enhanced parameters. Stem sealing is ensured by MG1241 (PTFE with fiberglass and graphite) or standard PTFE, supporting working pressures up to 103 bar and operating temperatures up to +186°C, depending on the chosen sealing material. Featuring GW NPT connections, a yellow lever with lock as standard, and optional oval levers, the valve combines safety, precision, and ease of use. Designed to operate in fully open or fully closed positions, it comes with a factory-adjusted packing seal for 70 bar, with the option of simple stem seal adjustment to match specific operating conditions, ensuring long-term reliability and efficiency in critical industrial processes.
