Industrial Flow Control Challenges
In industrial fluid systems, unstable flow is commonly caused by pressure fluctuations, variable load conditions, and the limited accuracy of manual or on/off control valves.
What This Valve Is Designed For
The Electric Proportional Flow Control Valve is designed for continuous automatic flow regulation based on control signals (4–20mA / 0–10V) from PLC or DCS systems.
It enables real-time adjustment of flow rate and supports integration with industrial automation systems requiring stable and repeatable performance.
Key Engineering Advantages
- Continuous proportional control (not on/off switching)
- Flow accuracy: ±1%–±2% (system dependent)
- Response time: ≤1–3 seconds
- Stable operation under pressure fluctuation conditions
- Compatible with PLC / DCS / SCADA systems
- Industrial low-leakage sealing structure
- Cycle life: ≥100,000 operations (laboratory test conditions)
- Optional feedback signal: valve position or flow output
