Features: 1. METAL DRIVER: Use metal transmission parts to drive the opening and closing of valves, which can be used for on-off control of heating and water supply systems. 2. VALVE COMPOSITION: The motorized ball valve consists of a pilot and a valve body, the pilot adopts a synchronous motor, which has no noise and has a constant action. 3. WITH SWITCH: The built-in limit switch can turn off the valve when it is fully open or fully closed, and equipped with a manual structure and is easy to adjust. 4. BRASS MATERIAL: The valve body is made of forged brass, with a sanding surface, which is wear and corrosion resistant, not easily deformed, and has a long service life. 5. WIDE APPLICATION: With equal percentage flow characteristics, 600KPA narrow differential pressure, widely used in heating, ventilation, air conditioning, refrigeration, etc. Specifications: Item Type: DN20 Ball Valve.
