Seeking help regarding the use of electric valves

Electric valves primarily use electric actuators to control the opening and closing as well as the regulation of valves, and are widely used in systems such as heating, ventilation, and air conditioning. During operation, the electric valve drives the actuator by receiving control signals, thereby enabling the opening or closing of the valve. Regarding identifiers like “O/S” that you mentioned, such identifiers usually denote specific functions or states. Specifically for electric valves, “O” usually denotes the “open” state, while “S” may refer to “stop” or a specific functional mode, depending on the manufacturer and model. Electric valves of different brands and types may have different markings and operating methods. If you are a beginner, it is recommended to: 1. Read and understand the product manual carefully, paying special attention to the sections on installation, operation, and maintenance. 2. Before using it for the first time, ensure that all connections are correct and configure it according to the instructions. 3. If you encounter confusion or problems during the process, do not hesitate to contact the supplier or seek help from a professional. Safety first; make sure to understand all the operating steps before proceeding. .

This is the electric actuator from Chongqing Chuanyi. ““LOC” indicates that the valve is set in the “local” operation mode; in this mode, the valve is opened by pressing the black button with an arrow pointing upward, and it is closed by pressing the black button with an arrow pointing downward ； When the switch button is set to “REM”, it indicates the “remote” operation mode, allowing valves to be opened and closed remotely from the PLC or DCS. “The “MODE” button, together with the black upward arrow button and the black downward arrow button, is used for setting valve parameters and calibrating the valve position.
