Jinghai Manual Worm‑Gear Actuator
Jinghai manual worm‑gear actuator is a manual emergency operating device for pneumatic valves. When air supply is cut off and the pneumatic actuator fails to work, it can manually open and close the valve via handwheel. Adopting worm‑gear transmission, it fits quarter‑turn valves such as butterfly valves and ball valves. Compact and easy‑to‑install, it can be combined with pneumatic actuators to ensure valve controllability. Widely used in chemical, building materials, water treatment, metallurgy and environmental protection industries.
Product Features
1. Worm‑gear transmission with good self‑locking performance, labor‑saving for manual valve operation.
2. Robust housing for harsh industrial working conditions.
3. Works with pneumatic actuators, enables manual operation in case of air‑supply failure to improve pipeline safety.
4. Handwheel marked with open/close directions for intuitive field operation.
5. Standard mounting interface, suitable for various quarter‑turn valves. Transmission ratio and mounting size can be customized.
6. Simple structure, easy maintenance and long service life.
