Smart Proportional Control Valve

Smart Proportional Control Valve is an industrial flow modulation device designed for precise and stable control in automated process systems. It integrates an electric actuator, control valve body, and intelligent positioning module to achieve continuous adjustment based on standard control signals (4–20mA / 0–10V) from PLC, DCS, or SCADA systems.
It is engineered for continuous process regulation applications where system stability, response accuracy, and repeatability are critical, such as HVAC systems, water treatment plants, and industrial energy systems.
Unlike conventional on/off valves, it enables dynamic proportional control to maintain stable system performance under variable load conditions.

• Continuous proportional modulation (0–100% positioning accuracy)
• High repeatability control performance for process stability
• Closed-loop feedback with real-time position correction
• Response time optimized for dynamic industrial systems (2–5s typical)
• Industrial-grade IP67 protection for harsh environments
• Optional fail-safe mode (spring return or backup power system)
• Compatible with PLC / DCS / SCADA industrial automation systems
• Designed for long-term operation (≥100,000 cycles)

• Actual control accuracy depends on system pressure differential and flow characteristics
• Proper actuator torque selection is required for high-pressure or large-diameter pipelines
• Recommended for modulation duty applications rather than frequent full shut-off cycling

The system operates through a closed-loop modulation control mechanism. A PLC or control system sends a target analog signal representing the desired process condition. The actuator continuously compares the input signal with real-time valve position feedback and adjusts motor output to eliminate deviation.
This ensures stable and accurate regulation even under fluctuating pressure, flow, or load conditions.

This valve is widely applied in industrial automation systems, including:

• District cooling and heating systems for commercial buildings
• Industrial HVAC chilled and hot water regulation systems
• Water treatment flow balancing and chemical dosing systems
• Industrial energy optimization and distribution systems
• Process control systems in manufacturing industries

In practical installations, it is commonly used in multi-zone flow control and variable load regulation systems.

• Improves system stability under variable flow conditions
• Reduces hydraulic shock and pressure fluctuations
• Enhances energy efficiency in HVAC systems
• Extends equipment service life through smoother operation
• Reduces maintenance frequency and operational cost
