The **ACV-D1122-R** is a specific part number typically associated with an **Electromagnetic Valve** (often used in HVAC systems, water control, or automotive applications). This specific model is a 2-way, normally closed solenoid valve designed for liquid or gas flow control. --- ### Technical Specifications The electronic and mechanical characteristics of the ACV-D1122-R are summarized in the table below: | Feature | Specification | | :--- | :--- | | **Valve Type** | Solenoid Valve (Electromagnetic) | | **Operating Mode** | Normally Closed (NC) | | **Coil Voltage** | Typically 110V - 120V AC (Standard for '11' series) | | **Body Material** | Often Brass or Engineering Plastic | | **Orifice Size** | 2.0mm to 3.0mm (Varies by sub-model) | | **Connection Type** | Threaded (NPT or G) | | **Pressure Range** | 0 to 10 Bar (approx. 145 PSI) | --- ### Key Electronic Components The ACV-D1122-R operates based on the interaction between its internal electronic parts: #### 1. The Solenoid Coil This is the heart of the unit. When an electric current (110V/120V AC) passes through the copper windings, it generates a magnetic field. * **Insulation Class:** Usually Class F or H (to withstand heat). * **Power Consumption:** Typically low (5W - 10W) for energy efficiency. #### 2. Armature/Plunger Assembly Inside the coil sits a movable ferromagnetic plunger. * **Mechanism:** When the coil is energized, the magnetic force pulls the plunger upward against a spring. * **De-energized:** The spring forces the plunger down to seal the orifice, stopping flow. #### 3. Wiring and Protection * **Lead Wires:** Usually color-coded (Black/White or Red/Red) for connection to the AC power source. * **Encapsulation:** The coil is typically epoxy-molded to protect the internal wiring from moisture, dust, and vibration. --- ### Application Usage This part is commonly found in the following systems: * **Water Purifiers:** To control the input flow of water. * **Medical Equipment:** For precise fluid or air delivery. * **Automation:** As an actuator in PLC-controlled pneumatic systems.
