The HOM Series quarter-turn electric actuators adopt planetary gear structure for mechanical transmission, with output torque ranging from 100 N·m to 8000 N·m. The manual operating mechanism features a clutchless design, so manual and electric operations do not interfere with each other, and the handwheel can be rotated even when power is supplied.This series is compatible with butterfly valves, ball valves, plug valves and other valve types, and widely used in pipeline systems of power plants, metallurgical plants, wastewater treatment plants, building automation, urban pipe networks, etc. It boasts high output torque, self-locking capability and a wide range of gear ratios. All connection flanges comply with ISO 5211 standard, and splined shaft couplings are adopted for easy matching with valves of various specifications.
