The **F2VS-C4-R** is a specific model within the **F2VS series of 2-way solenoid valves**, typically manufactured by companies like **CKD Corporation**. These valves are designed for high-purity chemical liquid control, often used in semiconductor manufacturing or medical laboratory equipment. ### 1. Part Number Breakdown To understand the electronic and mechanical nature of the device, we can decode the nomenclature: | Component | Code | Description | | :--- | :--- | :--- | | **Series** | F2VS | Fine System Valve (Chemical Liquid Valve) | | **Orifice** | C4 | 4mm internal orifice diameter | | **Operation** | R | Air-operated or NC (Normally Closed) logic (varies by specific manufacturer revision) | --- ### 2. Key Electronic & Technical Specifications The F2VS-C4-R is primarily an **Air-Operated Valve**, meaning its primary motive force is pneumatic, but it is often integrated into an electronic control circuit via a solenoid pilot valve. * **Actuation Type:** Pneumatic (Air-operated). * **Operating Pressure:** Typically ranges from 0 to 0.5 MPa. * **Pilot Air Pressure:** 0.35 to 0.5 MPa. * **Fluid Temperature:** Generally handles liquids between 5°C to 100°C (depending on the diaphragm material). * **Wetted Parts:** Usually constructed from **PFA** (Perfluoroalkoxy) or **PTFE**, ensuring zero metal ion contamination and high chemical resistance. --- ### 3. Electronic Integration Parts While the valve body itself is mechanical/pneumatic, its "electronic" aspect comes from the control interface: #### A. Solenoid Pilot Interface To automate this valve, it is usually connected to an external **3-port solenoid valve**. The electronic specs for the pilot are usually: * **Voltage:** 24V DC (Standard) or 100V/110V AC. * **Power Consumption:** Approx. 0.6W to 2W. #### B. Limit Switches / Sensors (Optional) Some versions of the F2VS series can be fitted with electronic position sensors: * **Proximity Sensors:** Used to confirm the "Open" or "Closed" state of the valve back to a PLC (Programmable Logic Controller). * **Connection:** Usually M8 or M12 circular connectors or lead wires. --- ### 4. Application Use-Cases The F2VS-C4-R is specifically engineered for environments where electronic components must be isolated from corrosive fluids: 1. **Semiconductor Wet Processing:** Handling photoresist, developers, or ultra-pure water. 2. **Chemical Dispensing:** Precise electronic control of hazardous acid/alkali flow. 3. **Solar Cell Production:** Managing high-purity coating fluids. ---
