What is the function of dynamic braking?

Dynamic braking prevents valve overshoot caused by large motor inertia by using an electric braking method.

How does the actuator handle signal faults?

It has a signal locking function that detects faults in the 4-20mA circuit and stays in situ or moves to a set location.

Key features

Overtorque Protection: Accurately measures torque and locks the actuator to protect the valve and motor from damage.

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

Absolute Encoder Control: Uses an absolute encoder for automatic stroke control without the need for micro switches.

4-20mA Position Feedback: Provides constant current output with 750 ohm impedance for accurate position indication.

Dynamic Braking: Standard electric braking prevents valve overshoot caused by excessive motor inertia.

Automatic Phase Detection: Three-phase wiring does not require phase sequence consideration, protecting against damage.

Signal Locking Function: Detects faults in the 4-20mA signal circuit and stays in place or moves to a 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.
