HEM MULTI TURN ACTUATOR
Introducing the HEM series, a cutting-edge line of multi-turn electric actuators meticulously crafted by the innovative minds at HeLi Company. Our HEM series embodies a perfect fusion of user-centric design and extensive development expertise. Available in a multitude of configurations, including basic, intelligent, bus-type, and intelligent split-type, the HEM series is engineered to deliver unparalleled safety, stability, and reliability, tailored to suit diverse application needs across a wide range of industries.
The HEM series multi-turn electric actuators are versatile and adaptable, making them ideal for use with linear stroke valves such as regulating valves, gate valves, and globe valves. Moreover, these actuators can seamlessly integrate with part-turn worm gearboxes, enabling compatibility with quarter turn valves, including butterfly valves, ball valves, and plug valves, thereby expanding their versatility across numerous applications.
To ensure optimal performance and longevity, it is recommended that the operational speed remains moderate when the actuator is directly mounted on gate valves, as the inertia effect and wear of the drive shaft sleeve can impact performance.
The maximum torque setting is calibrated for bi-directional operation at nominal torque levels. The locked torque is influenced by speed and voltage, typically
ranging from 1.4 to 2 times the nominal torque, allowing for robust operational flexibility.
For 60Hz orders, speed adjustments should factor in a 1.2 times increase for precise applications.
Our 380VAC/3PH systems, available in on-off and modulating types, support up to 600 starts per hour, with an optional 1200 starts for modulating units. Note: For basic types exceeding 36RPM, overtorque protection is not provided.
