The **M5MV-101-R** is a specific high-performance **Micro-Solenoid Valve** manufactured by **CKD Corporation**. These components are widely used in pneumatic control systems where precision, compact size, and rapid response times are critical. Below is a detailed breakdown of its electronic and mechanical parts, specifications, and applications. --- ### 1. Component Overview The M5MV series is characterized by its "Micro-Valve" design, intended for manifold mounting in automated machinery. | Feature | Specification | | :--- | :--- | | **Type** | 3-Port Solenoid Valve | | **Operation Type** | Direct Acting / Poppet Type | | **Fluid Type** | Compressed Air / Non-corrosive gas | | **Port Size** | M5 (Metric) | | **Standard Voltage** | 24V DC (Most common for -R suffix) | --- ### 2. Electronic & Internal Parts Breakdown The functionality of the M5MV-101-R relies on several key internal elements: #### A. The Solenoid Coil * **Function:** Converts electrical energy into magnetic force. * **The "R" Suffix:** In CKD nomenclature, the "R" often signifies a specific electrical connection type (typically a **Plug-in Connector** or a specific **Lead Wire** orientation) and often includes a **Surge Suppressor**. * **Power Consumption:** Designed for low wattage (typically around 0.6W to 1.0W) to reduce heat buildup and allow for PLC-driven control without high-power relays. #### B. The Armature (Plunger) * **Material:** Ferromagnetic stainless steel. * **Action:** When the coil is energized, the magnetic field pulls the armature upward, overcoming the return spring force to open the air path. #### C. Surge Suppressor (Internal) * Most models in this series include a **Flyback Diode** or **Varistor**. * **Purpose:** Protects the controlling electronics (like a PLC output card) from the inductive voltage spikes generated when the solenoid coil is de-energized. #### D. Manual Override * A small mechanical button or twist-lock located on the valve body. * **Use:** Allows technicians to trigger the valve manually during setup or troubleshooting without needing an electrical signal. --- ### 3. Technical Specifications | Parameter | Value (Typical) | | :--- | :--- | | **Operating Pressure Range** | 0 to 0.7 MPa (0 - 101 PSI) | | **Response Time** | < 10ms (On) / < 15ms (Off) | | **Proof Pressure** | 1.05 MPa | | **Ambient Temperature** | 5 to 50°C (41 to 122°F) | | **Electrical Entry** | Radial Lead Wire or Plug-in | --- ### 4. Common Applications Due to its small footprint and reliability, the M5MV-101-R is found in: 1. **Semiconductor Manufacturing:** For precise air-knife control or wafer handling. 2. **Medical Equipment:** Controlling small volumes of air in diagnostic devices. 3. **Pick-and-Place Robots:** Actuating small vacuum cups or miniature grippers. 4. **Pilot Valves:** Acting as a trigger for much larger pneumatic valves. ---
