1. Electronic Drain Valve of Automatic Drainer that Drains Water Regularly: This valve is an essential part of an automatic drainer, designed to discharge water at regular intervals. It ensures efficient water removal, preventing water accumulation and potential damage to the system. 2. Air Tank Valve: Controls the flow of air within the air tank. It helps regulate the pressure and distribution of air, playing a crucial role in maintaining the proper functioning of pneumatic systems that rely on the air tank. 3. Air Pump Solenoid Valve: Operates based on an electrical signal. It regulates the flow of air in the air pump, enabling precise control over the pumping process. This valve is vital for ensuring consistent and reliable air supply. 4. Kindly (Color : E): The word 'kindly' might refer to a specific quality or characteristic related to these valves. The indication of color 'E' could be used for identification, perhaps in a system where colorcoding helps distinguish different components. 5. These components work together to ensure the smooth operation of various systems. The electronic drain valve manages water drainage, the air tank valve controls air within the tank, the air pump solenoid valve regulates air flow in the pump, and the color coding might assist in easy identification and maintenance of the system.
