How is the stroke controlled?

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

What is the purpose of dynamic braking?

It prevents valve overshoot caused by large motor inertia by using electric braking to control motor operation and ensure accurate positioning.

Key features

Overtorque Protection: Locks actuator and protects valve/motor when torque exceeds set range with memory function.

High Frequency Starting: Special servo motor allows up to 1200 starts per hour with low inertia and high starting torque.

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

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

Automatic Phase Detection: Three-phase wiring requires no phase sequence consideration, protecting against phase extension damage.

Signal Locking Function: Stays in situ or moves to emergency location upon detection of 4-20mA analog signal faults.

Absolute Encoder Control: Enables automatic stroke setting without micro switches via drive shaft connection.

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.
