What happens if the signal is faulty?

The actuator has a signal locking function. If a fault is detected in the 4-20mA analog signal, it can stay in place or run to a set emergency location.

What is the lead time for production?

The average lead time is within 15 workdays, regardless of whether it is peak season or off-season.

Key features

Overtorque Protection: Locks actuator on signal when torque exceeds set range to protect valve and motor.

High Frequency Starting: Special servo motor allows up to 1200 starts per hour.

Dynamic Braking: Prevents valve overshoot caused by motor inertia using electric braking.

Automatic Phase Detection: Three-phase wiring does not require phase sequence consideration.

Position Feedback: Outputs 4-20mA DC current as position indicator with 750 ohm impedance.

Signal Locking Function: Stays in place or moves to set location if analog signal fault occurs.

Magnetic Switch Control: Enables local native operation without interconnecting shaft.

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 overtorque protection feature?

The actuator measures torque accurately. If it exceeds the set range, the torque switch sends a signal to lock the actuator, protecting the valve and motor. It resets automatically when the fault is eliminated.

Q:What is the starting frequency limit?

The special servo motor allows frequent starting, with a capacity of up to 1200 starts per hour.

Q:Does the actuator have dynamic braking?

Yes, dynamic braking is a standard configuration. It prevents valve overshoot caused by large motor inertia using an electric braking method.

Q:Is phase sequence important for wiring?

No, the automatic phase detection function protects the actuator and valve from damage, so phase sequence does not need to be considered for three-phase wiring.

Q:How is the valve position indicated?

The actuator outputs a 4-20mA DC current as a position indicator. The output impedance is 750 ohm.
