The NEXUS series of actuators are widely used in various fields such as water conservancy, construction, fire protection, power, petroleum, chemical industry, metallurgy, heat, and medicine. The product diversity and flexibility enable customers to select appropriate models according to actual working conditions and valve sizes. There are various models such as LMR-NQ, LMR-NQ, etc.
When choosing the actuators, customers should select suitable models based on information such as valve torque, working conditions, and valve size. It is recommended that when choosing an electric actuator model, 60% – 80% of the rated output torque of the actuator should be used as the working torque of the valve. If the application scenario is very important or the environment is complex, customers should provide design drawings and detailed parameters as much as possible for the company’s experts to review and recommend matching products.
