3-Piece Stainless Steel Ball Valve, BSPT Female Thread, H-510

This three-piece medium-pressure ball valve is engineered for the most demanding industrial environments, ensuring reliable performance in chemical, petrochemical, pharmaceutical, energy, and process engineering applications for both liquids and gases. Designed for direct pipeline installation, it offers a wide size range to guarantee optimal flow, exceptionally tight shut-off with minimal internal leakage of just 0.1 Ncm³/min, and long-lasting durability 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. The robust body, connections, ball, and stem are manufactured from premium AISI 316 stainless steel, while the lever is made of AISI 304 steel with a durable PVC coating, available in the standard yellow version or with ergonomic oval levers. The valve is equipped with a PTFE ball seal as standard, with advanced sealing options such as modified PTFE, PTFE with stainless steel powder, UHMWPE, or PEEK available for higher performance requirements. Stem sealing is ensured by MG1241 (PTFE reinforced with fiberglass and graphite) or standard PTFE, providing excellent resistance under pressure. With a working pressure of up to 103 bar and operating temperatures reaching +186°C (depending on sealing material), this valve guarantees safe and efficient operation. Featuring GW BSPT connections, factory-adjusted packing seals for 70 bar, and the option for easy stem seal adjustment, it delivers maximum reliability, safety, and flexibility for critical industrial processes.
