2″ Full Port Ball Valve, Quarter Turn Quick Shut Off Industrial Pipeline Valve
2″ full port ball valve adopts full bore structure & fast quarter-turn switch, complies with API 608, used for water treatment, petrochemical pipeline isolation.
Description
Product Introduction for 2″ Full Port Ball Valve
The 2‑inch full port ball valve belongs to the DN50 medium‑bore series. Its primary functions are to isolate pipeline media and to provide emergency shutoff in fluid systems. Adopting a full bore floating ball structure, the valve’s ball opening matches the inner diameter of the connecting pipe, so that when fully open, throttling pressure loss is virtually eliminated. Combined with a quarter‑turn (90°) actuation mechanism, it can achieve rapid flow interruption within seconds, effectively balancing water conveyance efficiency and pipeline safety.

Structural and Sealing Options
Two sealing variants are available: a PTFE seated ball valve (soft‑seal) for clean water and gas services, and a metal‑hardened seat for high‑temperature thermal oil or abrasive chemical slurries. An ISO 5211 top mounting pad is integrally cast on the valve body, allowing easy retrofit with actuators to convert it into an automated flanged ball valve – a feature well suited for smart pipeline control upgrades.
Application Scenarios & Case Reference
These valves are widely used in municipal water supply, petrochemical circulating water, HVAC systems, and biopharmaceutical fluid transfer lines. For example, the Tampere municipal clean‑water distribution station (Tekniikankatu 12, 33720 Tampere, Finland) has extensively installed 2″ full port ball valves on its branch supply pipes. Thanks to the full‑bore geometry, pumping energy is significantly reduced; during maintenance, the fast on‑off action isolates sections promptly, greatly shortening service interruption periods. Every finished valve undergoes both hydrostatic and pneumatic leak tests prior to shipment, and holds CE and API certifications. Corrosion‑resistant body coatings can also be customized based on the specific corrosiveness of the service medium.
