Multi-Turn MDF Kit Valve Activator for Industrial Gate and Globe Valves with High-Resolution Positioning

Product Description:
The Multi-Turn MDF Kit Valve Activator is the definitive solution for automating industrial gate valves, globe valves, and other process valves that require multiple rotations of the stem to transition from fully open to fully closed. This powerful electric actuator is engineered to deliver thousands of turns with unwavering torque and precise control, making it essential for precise flow modulation in critical applications such as power generation, chemical processing, and water distribution networks. Its key feature is high-resolution positioning, allowing it to stop and hold the valve at any intermediate point with exceptional accuracy. This capability is crucial for throttling applications where fine control over flow rate, pressure, or level is required. The actuator is equipped with a non-intrusive local control interface and advanced diagnostics, enabling easy setup and maintenance without opening the weatherproof enclosure. Built with a robust industrial-grade gearbox and a thermal-protected motor, it is designed for long-term reliability in the harshest environments. The Multi-Turn MDF Kit Valve Activator provides the muscle and intelligence for complete and precise control over your most demanding process valves.

Bullet Points:

• Designed for precise automation of industrial gate and globe valves.

• Provides high-resolution positioning for accurate flow throttling.

• Capable of delivering high thrust over multiple thousands of turns.

• Features non-intrusive infrared setup and diagnostics.

• Robust IP67 enclosure ensures reliability in harsh outdoor and industrial settings.

Specific Application Scenario
In a chemical processing plant, this activator is used to precisely control a large globe valve on a reactor feed line, accurately throttling the flow of a raw material to maintain a specific reaction rate and product quality.

Factory Production Floor
The assembly line for multi-turn actuators includes a run-in station where each unit is cycled through its full range of turns under load. A laser encoder verifies the high-resolution positioning accuracy, and the data is logged for quality assurance.

Packing and Transportation
The actuator is mounted on a sturdy wooden pallet with its stem coupling protected by a custom-made steel cover. The entire unit is then shrink-wrapped to secure it to the pallet for heavy-duty shipping.

FAQ
1. What is the difference between a quarter-turn and a multi-turn actuator?
Quarter-turn actuators rotate 90 degrees for valves like ball and butterfly valves. Multi-turn actuators are designed for industrial gate and globe valves that require many rotations (e.g., 1000+) to open or close.

2. How is the high-resolution positioning achieved?
It uses a high-precision encoder that counts thousands of pulses per revolution, allowing the control system to determine the valve's exact position with great accuracy for precise high-resolution positioning.

3. Can it be manually operated if power fails?
Yes, all our multi-turn models include a declutchable manual override, typically a handwheel, allowing for safe manual valve operation during power outages or maintenance.

4. What is the maximum thrust output?
Thrust outputs vary by model, with our heavy-duty series capable of delivering over 100,000 lb-f, sufficient for the largest industrial gate and globe valves.

5. How does it communicate with the control system?
It offers a range of options from simple contact closures to advanced digital fieldbus protocols (Profibus, Modbus, Foundation Fieldbus) for seamless integration into a Plant Control System.
