| Parameter Category | Key Parameters | Typical Range/Specification | Selection Notes |
| Pressure Parameters | Maximum Inlet Pressure | 0.8 MPa ~ 20 MPa | High-pressure gas cylinders select 15-20 MPa, pipeline gas sources select 0.6-1.0 MPa |
| Outlet Pressure Range | 0~0.2 MPa to 0~1.2 MPa | Select the adjustable range according to process requirements | |
| Rated Working Pressure | 0.3 MPa ~ 0.6 MPa | Common working range | |
| Withstand Pressure | More than 1.5 times the inlet side | Ensure safety under overpressure conditions | |
| Flow Parameters | Flow Coefficient (Cv Value) | 0.03 ~ 0.7 | Select 0.03 for small flow, 0.7 for large flow |
| Maximum Flow Rate | 10 mL/min ~ 100 m³/h | Small flow for laboratory use, large flow for industrial use | |
| Flow Control Accuracy | ±0.5% ~ ±2% FS | Choose MFC for high precision, can be relaxed for general industry | |
| Allowable Leak Rate | ≤0.6 L/h | Industrial-grade gas line sealing requirements | |
| Electrical Parameters | Power Supply | 220VAC/50Hz or 24VDC | Use 220V for PLC system, 24V for sensors/ solenoid valves |
| Rated Power | 8.5W ~ 500W | Determined by the number of control components | |
| Control Mode | Manual/Semi-automatic/PLC Automatic | PLC enables remote monitoring and data recording | |
| Control Signal | 0-5V, 0-10V, 4-20mA | Analog control interface | |
| Communication Interface | RS485, Ethernet, Profibus | For remote monitoring and system integration | |
| Display Method | Touchscreen, LED, analog gauge | On-site monitoring and parameter setting |
