Product Overview
Electric Control Valve is an industrial automation valve designed for continuous and precise regulation of flow, pressure, temperature, or level in process systems.
It is driven by an electric actuator and integrated with PLC / DCS control systems to achieve closed-loop process regulation, ensuring stable performance under dynamic operating conditions.
Engineering Working Principle
The system operates in a closed-loop control structure:
- PLC / DCS sends control signal (4–20mA / 0–10V / Modbus RTU optional)
- Electric actuator converts signal into precise angular motion
- Valve element adjusts flow passage proportionally
- Position feedback ensures real-time accuracy and stability
This enables continuous regulation of:
- Flow rate (Kv/Cv control)
- Pressure balance
- Temperature stability in process systems
Engineering Selection Parameters
To ensure correct valve selection in engineering applications, the following parameters must be defined:
EN:
- Flow capacity (Kv / Cv value)
- Operating pressure differential (ΔP range)
- Media type (water / steam / oil / chemical / slurry)
- Operating temperature range
- Required control accuracy (±%)
- Leakage class (ANSI FCI 70-2 Class IV / VI optional)
- Actuator torque requirement
- Pipeline size (DN / NPS)
Engineering selection support is available for actuator sizing and valve configuration.
Verified Project Applications
Our electric control valves are applied in industrial process systems requiring long-term stable modulation performance.
Verified application scenarios include:
- HVAC chilled water systems in commercial buildings (Germany / UAE projects, DN50–DN300 range)
- Chemical dosing and mixing control systems in Southeast Asia industrial plants (corrosive media control conditions)
- Steam flow regulation systems in thermal power generation units (high temperature and pressure conditions)
- Reverse osmosis desalination and water treatment systems (continuous duty operation)
- Automated industrial production process control systems (multi-point flow regulation)
