Safe storage and transfer at tank farms depend on the fast and reliable operation of valves. Hengchun's electric, pneumatic, and Gas-over-Oil actuators deliver high torque output and rapid response for tank isolation valves, line switching valves, and Emergency Shutdown (ESD) valves. Integrated ESD functionality and a fail-safe mode automatically trigger in emergencies, minimizing risk. They are core components for depot automation and safety systems.
