The Quarter Turn Worm Gearbox – Actuator Operation is a heavy-duty, export-quality gearbox designed for use with electric or pneumatic actuators to operate quarter-turn valves such as ball valves, butterfly valves, and plug valves.
Manufactured by Relekon Automation, this gearbox is engineered for high torque transmission, operational reliability, and long service life, making it ideal for OEM actuator integration, EPC projects, and international industrial supply.
Precision-machined components and a robust worm gear mechanism ensure smooth torque multiplication, accurate valve
positioning, and dependable performance under demanding operating conditions.
