The **KADS-GZ-R** series typically refers to a specific line of **Electromagnetic Solenoid Water Valves** often used in industrial automation, water treatment, and home appliances. These components are electromechanical devices designed to control the flow of liquids. Below is a detailed breakdown of its electronic and mechanical components. --- ### 1. Key Technical Specifications Most KADS-GZ-R models share the following electronic characteristics: | Component Feature | Description | | :--- | :--- | | **Voltage Options** | Usually DC 12V, DC 24V, or AC 110V/220V | | **Operation Mode** | Normally Closed (NC) - Opens when powered | | **Connection Type** | Male Thread (G1/2" or G3/4") | | **Power Consumption** | Approx. 4.5W to 8W (depending on voltage) | | **Pressure Range** | 0.02 Mpa to 0.8 Mpa | --- ### 2. Internal Electronic Parts The device functions through the interaction of several critical electronic and magnetic parts: #### A. The Electromagnetic Coil (Solenoid) This is the heart of the device. It consists of a copper wire wound around a bobbin. * **Function:** When current flows through the coil, it creates a magnetic field according to Ampere's Law. * **Insulation:** Usually rated Class B or F to withstand heat generated during long-term operation. #### B. The Plunger (Armature) A movable cylinder made of ferromagnetic material (usually stainless steel). * **Function:** It is pulled upward by the magnetic field of the coil, overcoming spring tension to open the valve orifice. #### C. Terminals / Connector * **Interface:** Usually features 6.3mm spade terminals or a lead wire exit. * **Polarity:** For DC models, polarity is generally not critical unless a protection diode is integrated, but it is best practice to follow manufacturer markings. --- ### 3. Functional Mechanism The KADS-GZ-R operates as a **Pilot-Operated** valve. This means it uses the electronic solenoid to control a small "pilot" hole, which then uses the water pressure itself to lift a rubber diaphragm. 1. **Power OFF:** The spring pushes the plunger down, blocking the pilot hole. Water pressure stays high above the diaphragm, keeping the valve closed. 2. **Power ON:** The coil energizes, lifting the plunger. The pilot hole opens, relieving pressure above the diaphragm. The pressure from below pushes the diaphragm up, allowing full flow. --- ### 4. Typical Applications * **Water Purifiers:** Controlling the inlet feed. * **Smart Agriculture:** Automated drip irrigation systems. * **Vending Machines:** Precise liquid dispensing. * **Washing Machines:** Managing water intake cycles. --- ### 5. Safety & Maintenance Notes * **Heat:** Solenoids get hot during continuous operation. Ensure the duty cycle (on-time vs. off-time) matches your application. * **Filtration:** Because the pilot holes are very small, these valves require clean water. Debris can cause the valve to "stick" open or closed. * **Voltage Tolerance:** Usually +/- 10% of the rated voltage.
