The Li Jin Industrial Co. is a veteran developer of high-quality and -durability actuator products, including quarter-turn actuators, spring return actuators, and linear actuators.
The firm's actuators are designed for the actuation of ball valves, butterfly valves, plug valves, and dampers, and other devices used in a wide array of applications such as water, temperature, water treatment, irrigation, chemical engineering, food-making, and other control systems.
The company developed spring-return actuators that, in addition to their usual functions, can provide the fail-safe positioning of valves and dampers in case of power outage.
A mechanical spring set is utilized to position the controlled device to either the fully Open or fully Closed position without any external power source.
Li Jin's linear actuators, according to the company, provide thrust from 250 to 2,000 kgs and a starting operation frequency that can be set at up to 1,500 starts per hour. All models are equipped with modularized controllers for globe valves, gate valves, and linear travel devices. The company's linear valve actuators can be widely used in HVAC (heating, ventilation, and air conditioning) and other industrial applications, especially in environments with steam and high temperatures.
Li Jin devotes itself into the highest standards of company management and product quality, and has been approved by the most stringent international quality-assurance systems including ISO 9001, ISO 14001, and OHSAS 18001. Its products conform to all CE, CSA, and RoHS standards, reflecting the firm's long-term pursuit of excellence.
Besides, Non-clutch and brake manual operation without any lever, clutch or brake upon power outage also won new type patent in Taiwan, China and USA.
The innovative firm has also developed a new product line: gear motors for crane saddle seats. These products have won SGS, CCC, and UKAS certification.
And damper design also won the new patent. High temperature application up to 300ﾟC
This company not only provides its in-house-designed products but also welcomes OEM/ODM projects.
