Electric Control Valve

Description

Overview of KNKE Electric Control Valve

The KNKE NCRV Series Electric Control Valve utilizes a sleeve-guided, pressure-balanced valve plug, designed for applications with large pressure differentials. The improved sleeve single-seat design enhances leakage control, while the S-shaped flow passage minimizes pressure drop and offers high flow capacity. This valve is equipped with the 381 series actuator, providing large output force in a compact structure. It is suitable for high-pressure differential, low-temperature, and high-reliability applications in industries such as chemical, gas, power, paper, food, metallurgy, and mining.

Key Features of KNKE Electric Control Valve

  • Compact Design: Efficient, small-size actuator with high output force.
  • Pressure Balanced Valve Plug: Reduces the required actuator thrust, making it suitable for high-pressure differential applications.
  • Improved Leakage Control: Sleeve single-seat design significantly reduces leakage, ensuring reliable performance in demanding conditions.
  • Wide Adjustment Range: Capable of handling a wide range of flow rates with minimal pressure loss.
  • High Reliability: Suitable for use in industries requiring strict control and high-performance valve characteristics.
  • Material Versatility: Broad material selection allows for customization based on specific industry requirements.
