Based on your query, the **YVD-Z-R** code typically refers to a specific configuration of a **Pressure Reducing Valve (PRV)**, often associated with brands like *Yoshitake* or similar industrial manufacturers. While the body is mechanical, the "Electronic Parts" generally refer to the sensing and control peripherals attached to it. Below is a breakdown of the electronic and electromechanical components typically associated with this model series. --- ### 1. Core Electronic Components In an automated or monitored pressure system, the YVD-Z-R interacts with several electronic modules: | Component | Function | Technical Detail | | :--- | :--- | :--- | | **Pressure Transmitter** | Monitors downstream pressure. | Usually 4-20mA or 0-10V output. | | **Solenoid Pilot** | Remote ON/OFF control. | 24V DC or 110V/220V AC coils. | | **Limit Switches** | Indicates if the valve is open/closed. | SPDT or DPDT dry contacts. | | **Positioner** | (If motorized) Modulates the valve opening. | Uses feedback loops to match setpoints. | ### 2. The "Z-R" Suffix Interpretation In industrial nomenclature for these valve types: * **Z (Feedback/Sensor):** Often indicates the presence of a remote sensing line or an electronic pressure feedback port. * **R (Remote Control):** Suggests the valve can be adjusted remotely via an electronic pilot or a pneumatic-electric transducer. --- ### 3. Electrical Specifications If your specific unit is the **Solenoid-Actuated** version, the electronic specifications are as follows: ```yaml Electrical_Specs: Voltage_Options: [24VDC, 100VAC, 200VAC] Power_Consumption: 15W - 25W (Average) Insulation_Class: Class B or H Protection_Rating: IP65 (Dust and Water Jet resistant) Connection: DIN Connector or Lead Wires ``` --- ### 4. Integration Logic The electronic parts operate in a closed-loop system: 1. **Sensor Input:** An electronic pressure sensor detects that the downstream pressure has dropped. 2. **Controller Action:** A PLC or PID controller sends a signal to the **YVD-Z-R's** electronic pilot. 3. **Mechanical Execution:** The solenoid or motor adjusts the tension on the internal spring/diaphragm to restore the desired pressure.
