Multi-Turn Electric Actuator – EMD Series Integration Type

Short Description:

The EMD series multi-turn electric actuator delivers output rotation beyond 360°, designed for multi-turn and linear-motion valves such as gate valves, globe valves and control valves. Paired with a 90° worm gearbox, it can also operate quarter-turn valves including butterfly, ball and plug valves. The range spans from basic models for general industrial applications to intelligent models with advanced configuration and feedback options — a solution for virtually every valve automation need.

Advantage

Warranty: 2 years
Motor Protection: An F-class insulated motor is equipped with two temperature sensors to prevent overheating. (Class H motor can be customized)
Anti Moisture Protection: It also has a standard anti-moisture feature to protect internal electronics from condensation.
Absolute Encoder: The motor features a 24-bit absolute encoder that can accurately record up to 1024 positions, even in the event of a power loss. Available in both integration and intelligent types.
High Strength Worm Gear and Worm Shaft: The motor also boasts a high-strength alloy worm shaft and gear for increased durability. The meshing between the worm shaft and gear has been carefully examined to ensure maximum efficiency.
High RPM output: The motor's high RPM makes it ideal for use with large diameter valves.
Non-Intrusive set up: The integration and intelligent types can be remotely controlled and come with an LCD display and local control buttons/knobs for easy access. Valve position can be set without the need to manually open the actuator.
Performance Processor: The intelligent type utilizes a high-performance microprocessor, allowing for efficient and reliable monitoring of valve position, torque, and operational status.
