It appears you are referring to the **AM-MLP-VAL-JS** component, which is typically identified as an **Electronic Water Level Control Valve** or a **Solenoid Valve Assembly** often used in appliances like washing machines or water purification systems. Below is a breakdown of the electronic and mechanical parts that make up this component. --- ### 1. Component Overview The device is an electromechanical actuator that uses an electrical signal to control the flow of a fluid (usually water). | Part Name | Function | | :--- | :--- | | **Solenoid Coil** | Converts electrical energy into magnetic force to move the plunger. | | **Plunger/Armature** | The internal rod that physically opens or closes the valve orifice. | | **Diaphragm** | A flexible seal that maintains pressure and prevents leakage. | | **Terminals (JS)** | The electrical connection points (often JST or spade connectors). | | **Return Spring** | Forces the valve back to its "Normally Closed" (NC) position when power is cut. | --- ### 2. Deep Dive: Electronic Parts #### A. The Solenoid Coil (The "Actuator") The heart of the unit is a copper wire coil wrapped around a bobbin. * **Operating Voltage:** Usually 12V DC, 24V DC, or 110V/220V AC depending on the specific model variation. * **Impedance:** The coil has a specific resistance (measured in Ohms) that determines the current draw. * **Inductance:** When energized, it creates a magnetic field that pulls the metallic plunger upward. #### B. Electrical Connectors (JS Specification) The "JS" in the part number often refers to the **JST (Japan Solderless Terminal)** style connector. * **Pin Pitch:** Usually 2.0mm or 2.5mm. * **Security:** These connectors often feature a locking mechanism to prevent disconnection due to machine vibrations. #### C. Internal Protection (Optional) Some high-end versions include: * **Flyback Diode:** To prevent voltage spikes when the coil is de-energized. * **Thermal Fuse:** To shut down the valve if the coil overheats due to a jam. --- ### 3. Functional Specifications | Feature | Description | | :--- | :--- | | **State** | Normally Closed (NC) — No flow without power. | | **Media** | Water or neutral fluids. | | **Pressure Range** | Typically 0.02 Mpa to 0.8 Mpa. | | **Body Material** | Often PP (Polypropylene) or Nylon for heat resistance. | --- ### 4.
