Key features

Overtorque Protection: Built-in torque switch locks actuator if torque exceeds set range, protecting valve and motor from damage.

High Starting Torque Motor: Special servo motor allows frequent starting up to 1200 times per hour with low rotary inertia.

Precise Position Control: Uses absolute encoder for automatic stroke control without micro switches, ensuring accurate positioning.

4-20mA Signal Output: Provides constant current output with 750 ohm impedance for precise position feedback and signal comparison.

Dynamic Braking System: Standard electric braking prevents valve overshoot caused by motor inertia, ensuring accurate valve positioning.

Automatic Phase Detection: Three-phase wiring does not require phase sequence consideration; auto-detection protects against phase damage.

Signal Fault Locking: Automatically detects 4-20mA signal faults and stays in current position or moves to set emergency location.

AI-Powered supplier vetting

SummaryTianjin Freya Automation Technology Co., Ltd. is a nine-employee limited company focused on intelligent electric actuating mechanisms. It reports OEM and ODM services, flexible customization, annual productivity of 10,000 electric actuator sets, a valid import/export license, CE and other product certifications, and ISO9001:2015 certification. Its export sales share is stated as 71%–90%, and it reports a 50%–80% repeat-buyer preference. Service procedures and complaint-handling procedures exist, although some supplier-service documentation lacks records or approval signatures/dates. Innovation evidence is limited: one R&D engineer, no new products in the previous year, and no available SDK. Overseas warehouses, showrooms, agents or branches, and offline trade-show participation are explicitly absent. Quality-assurance status, traceability, and the status of test-equipment identification are not sufficiently established; the stated quantity of quality-control test equipment is 0.

Supplier typeThe supplier is a limited company with nine employees and no stated parent group or affiliated company. Its stated business centers on intelligent electric actuating mechanisms, and it provides OEM and ODM services, indicating a manufacturer-oriented supplier profile.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE plus other product compliance certifications. These are explicit certifications relevant to management and product conformity.

After-Sales capabilityThe supplier states that it provides pre-sales and after-sales service, has a clear customer-complaint procedure with followed records, and maintains a corrective and preventive action procedure with records. However, its service-capability assessment procedure has no records, and its approved supplier list lacks approval signatures or dates; it also has no overseas warehouse, showroom, agent, or branch.

R&D capabilityThe supplier offers R&D-based design services and ODM capability, but it has no available SDK, launched no new products in the previous year, and reports only one R&D engineer. These findings show customization-oriented development capability but limited evidence of recent product innovation.

Production capacityThe supplier reports annual productivity of 10,000 electric actuator sets and holds a valid import/export license, while its export sales share is stated as 71%–90%. However, it reports zero quality-control test equipment, and quality-assurance and traceability statuses are unknown, creating a significant production-control concern.

Customization capabilityThe supplier explicitly provides minor customization, customization from samples and designs, full customization, and flexible customization. It also reports ODM capability, directly supporting a broad customization offering.

Product Q&A

Q:What is the maximum starting frequency of the motor?

The special servo motor is designed for frequent starting and is allowed to start up to 1200 times per hour.

Q:How does the actuator protect against overtorque?

It features a torque protection measurement that sends a signal to the control circuit when torque exceeds the set range, locking the actuator to protect the valve and motor.

Q:Is phase sequence important for wiring?

No, the actuator has an automatic phase detection function, so three-phase wiring does not need to consider phase sequence.

Q:What is the output signal type for position indication?

The actuator provides a 4-20mA DC constant current output with an impedance of 750 ohms for position feedback.

Q:How is the stroke controlled?

Stroke control is based on an absolute encoder mounted on the actuator, connected via accelerating gears, allowing automatic setup without micro switches.
