The **SVB-4WE-R/E** is a specific model within the **SVB Series** of high-performance solenoid valve manifolds, typically manufactured by companies like **CKD Corporation**. This part is crucial in pneumatic automation systems for controlling the flow of compressed air. --- ### 1. Part Number Breakdown To understand the electronic and mechanical functions, it is helpful to decode the nomenclature: | Segment | Identification | Description | | :--- | :--- | :--- | | **SVB** | Series Name | High-speed, high-frequency response solenoid valve. | | **4** | Valve Width/Size | Refers to the physical body size and flow capacity (Cv factor). | | **W** | Actuation Type | Often indicates a double-solenoid or specific manifold mounting type. | | **E** | Connection Type | Usually refers to integrated E-connector (D-sub or serial) for wiring. | | **R/E** | Options | Indicates specific coil ratings, surge suppressors, or RoHS compliance. | --- ### 2. Key Electronic Specifications The "R/E" variant typically emphasizes specific electronic protections and energy efficiency. * **Rated Voltage:** Usually 24V DC (Standard for PLC control). * **Power Consumption:** Designed for low wattage (approx. 0.6W to 1.0W) to allow direct driving from PLC output cards without external relays. * **Surge Suppressor:** Includes an internal **Varistor or Zener Diode** to prevent "back EMF" (voltage spikes) from damaging sensitive electronic controllers when the coil is de-energized. * **Indicator LED:** Integrated Red or Green LED to provide visual feedback on the valve's excitation status. --- ### 3. Functional Applications These parts are used in high-speed environments where electronic precision is required: 1. **High-Speed Sorting:** Fast response times (often <10ms) for ejecting defective parts on a conveyor. 2. **Pick and Place:** Controlling vacuum or pneumatic grippers in robotic cells. 3. **Medical Equipment:** Precise air dosing or pressure control. --- ### 4. Wiring and Connectivity The **E-connector** type simplifies the electronic interface by grouping multiple valves into a single cable assembly, reducing the "spaghetti wiring" often found in traditional pneumatic cabinets. ```yaml Wiring Configuration (Standard D-Sub): - Pin 1-20: Individual Solenoid Signals (L+) - Pin 21-25: Common Ground (COM-) - Protection: IP65/IP67 (when properly connected) ```
