SR13 series electric valve is mainly used for central air-conditioning cold and hot water system, which can accurately control the flow of cold and hot medium according to actual needs, and will not cause sudden changes in temperature to achieve the purpose of real-time accurate control of room temperature.
This manual introduces the SINRO SR13 series electric valve, describing its high‑precision proportional control, bidirectional operation, and optional timer function to extend service life. It outlines the valve's suitability for central air‑conditioning water systems and its resistance to temperature and humidity extremes.
The document lists technical data such as rated voltage, power consumption, supported AC input voltages, control signal ranges, connection sizes (DN15‑DN32), and provides wiring diagrams for public, power, and control terminals, along with installation guidance. This manual is written in Chinese.
