Key Parameters

  • Main parameters include nominal diameter, flow coefficient, adjustable range, drive mode, power supply voltage, and protection grade:
  • Nominal Diameter: This is the inlet and outlet diameter of the electric control valve, determining its flow capacity. Choose a suitable nominal diameter based on actual needs.
  • Flow Coefficient: A measure of the valve’s flow capacity, which is related to the nominal diameter. A higher flow coefficient indicates a stronger flow capacity.
  • Adjustable Range: An important performance index of the valve, indicating the range of flow it can control within its rated stroke. A larger adjustable range means broader control capabilities.
  • Drive Mode: Includes mechanical electric, smart, or digital electric actuator. Select based on actual needs and site conditions.
  • Power Supply Voltage: Common voltages include AC220V, 380V, or DC24V. Consider site power conditions when choosing.
  • Protection Grade: Indicates the valve’s dust and water resistance, essential for suitability in harsh environments.

Selection Based on Operational Conditions

When selecting an electric control valve, consider the operating conditions such as medium type, working pressure, and temperature:

  • Medium Type: The type of medium greatly affects the performance and structure of the valve. Corrosive media require corrosion-resistant materials or protective measures.
  • Working Pressure: Influences the performance and lifespan of the valve. High pressures necessitate high-strength materials and structures.
  • Working Temperature: Affects the materials and sealing performance of the valve. High temperatures require materials and seals that can withstand the heat.

Electric Actuator Basics

  • Power Supply: Options DC24V, AC220V, AC380V.
  • Input Control Signal: Typically 4-20MA or DC1-5V.
  • Feedback Control Signal: Usually DC4-20MA (load resistance under 500 ohms).

Electric control valves receive signals from automation control systems (e.g., 4~20mA) to adjust the valve and control parameters such as flow, temperature, and pressure, enabling automated adjustment.

Flow Characteristics and Selection

Flow characteristics of electric control valves include linear, equal percentage, and parabolic options, each suitable for different applications based on required control precision and stability.

Equal Percentage Characteristics

The relative stroke and flow of the equal percentage characteristic are not linear. This occurs because the flow change at any stroke point is proportional to the flow at that point, and the percentage change in flow remains consistent. As a result, when the flow is small, the change is minimal; when the flow is large, the change is significant, providing the same precision of adjustment at different openings.

Linear Characteristics

The relationship between the relative stroke and flow for linear characteristics is linear. The flow change caused by any unit change in stroke is constant. This means that large flows result in minor relative changes, and small flows result in significant relative changes.
