YNTO Achieves SIL3 Certification for Electric Actuators

Guangdong Yuantong Industrial Technology Co., Ltd. (YNTO) – a national‑level high‑tech enterprise in Dongguan known for its fluid‑control expertise – has announced that its electric actuator range has obtained a Functional Safety (SIL) certificate from Ente Certificazione Macchine. The certificate (No. 6C260429.GYIDU88) identifies YNTO’s YT‑series and EA‑series electric actuators and confirms that they comply with IEC 61508:2010 Parts 1‑7. According to the document, the actuators achieve Systematic Capability 3 (SIL 3) and “Type A element” random capability; they are designed to detect a loss of control signal in real time and automatically move to a preset safe position. ECM notes that the devices meet the requirements for safety‑related systems up to SIL 3 and must be integrated according to the safety manual.

Founded in 2009, YNTO specialises in the design, manufacture and service of fluid‑control valves and actuators capable of handling extreme temperatures, high pressures and corrosive media. The company has accumulated more than ten patents and holds ISO 9001, ISO 14001, ISO 45001 and CE certifications. Its main products – including pneumatic valves, electric valves, regulating valves and IoT electric valves – provide system‑integration solutions for fluid transport and control. These products are widely applied in water treatment, energy, semiconductor, chemical, metallurgy, food and pharmaceutical industries, and the firm emphasises a customer‑centric approach to innovation and quality.

Safety integrity levels are increasingly important in automation. Technical guidelines note that international standards such as IEC 61508 influence the design of programmable logic controllers and electric valve systems to meet SIL requirements. Compliance is a prerequisite for industries governed by ANSI, ASME, API, ISO and DIN specifications. By earning the SIL 3 certificate, YNTO demonstrates that its actuators can be used in safety‑instrumented functions where fail‑safe operation is critical. The certification not only affirms product reliability and functional safety but also underlines YNTO’s commitment to global quality standards and positions the company to better serve international process industries.
