Manual Worm Gear Actuators
The Manual Worm Gear Actuator is a specialized auxiliary mechanism designed to provide manual operation capability when air supply is unavailable or when precise human intervention is required. Using a worm-and-gear transmission system, the mechanism delivers increased torque and exceptionally stable movement, ensuring reliable valve opening, closing, and position adjustment. Its housing is made of high-strength aluminum alloy or ductile iron, while the internal gears are precision-machined to ensure durability and smooth transmission. The ergonomic handwheel or lever enables operators to maintain accurate control even during emergency conditions. A robust linkage system allows seamless switching between automatic pneumatic actuation and manual operation, and a safety-lock feature helps retain the desired valve position. This manual override mechanism is widely used in industries such as petrochemical processing, pharmaceuticals, food production, and water treatment. It is ideal for systems requiring both automated functionality and manual redundancy, offering an additional layer of operational safety and ensuring continuous reliability in demanding industrial environments.
