Product Performance
- High-precision regulation: Non-contact position detection combined with microprocessor control ensures valve positioning accuracy ≤±0.5% full scale, meeting high-precision process control requirements.
- Fast response: Response time to input signal changes is ≤0.5 seconds, which can quickly adapt to working condition changes and reduce regulation lag.
- Wide environmental adaptability: Operating temperature range of -40℃ to +85℃ and IP66/IP67 protection class enable stable operation in extreme climates, dust and humid environments.
- Intelligent diagnosis: Built-in self-diagnosis module can detect faults such as valve jamming and air supply abnormality, and feed back through HART protocol for easy maintenance.
- Energy-saving design: Adopts low-power solenoid valve with low air consumption, saving more than 30% energy compared with traditional positioners
