Vanne à boisseau sphérique à tourillon entièrement soudée à commande pneumatique

The fully welded trunnion ball valve with pneumatic control is engineered for underground pipelines, natural gas distribution, and high-pressure transmission systems where zero leakage and long-term reliability are critical. Its fully welded body eliminates potential leak paths at body joints, enhancing pressure containment and corrosion resistance—especially important for buried or inaccessible installations. The trunnion-mounted design ensures reduced operating torque and stable sealing even under high differential pressure. Equipped with a pneumatic actuator, the valve can be operated remotely for quick shut-off or flow regulation, making it ideal for emergency shutdown systems and automated process control. This combination of robust construction and automation improves operational safety, minimizes maintenance, and supports rapid response in critical situations. With fewer external leak points and low maintenance needs, it is a preferred solution in pipeline networks demanding high integrity and reliability over decades of service.
