HEM MULTI TURN ACTUATOR
Behold the HEM series, a revolutionary leap in multi-turn electric actuators, meticulously crafted by the proficient technical team at HeLi Company. This innovative series seamlessly fuses user-centric design with decades of developmental expertise. The HEM series offers an array of customizable models - from basic to intelligent, bus-type to intelligent split-type - each engineered to deliver uncompromising safety, unwavering stability, and unrivaled reliability. Whether you operate in industrial, commercial, or specialized sectors, the HEM series is your adaptable partner for diverse application scenarios.
The versatility of the HEM series multi-turn electric actuators is unparalleled. Whether your need is for linear stroke valves like regulating, gate, or globe valves, the HEM series is your ideal choice. Additionally, these actuators can be perfectly paired with part-turn worm gearboxes to efficiently work with quarter turn valves, including butterfly, ball, and plug valves. This adaptability makes the HEM series an indispensable tool for various valve operations.
To ensure optimal performance and longevity, it is advisable to moderate the running speed, particularly when the actuator is directly installed on a gate valve. This consideration accounts for the inertia effect and the drive shaft sleeve wear. is directly installed on the gate valve.
The actuator's dual-direction torque settings are calibrated at its nominal torque. Notably, the locked torque is influenced by speed and voltage, typically reaching 1.4-2 times the nominal torque to handle demanding operations with ease.
it's 1.4-2 times of the nominal torque.
For orders requiring 60Hz, enhance the speed by 1.2 times to achieve optimal efficiency.
The 380VAC/3PH actuator is available in on-off and modulating types, designed for a rigorous 600 starts per hour, or opt for an impressive 1200 starts per hour for the modulating variant. Note: For basic types exceeding 36RPM, overtorque protection is not provided.
