summary
The electric sleeve regulating valve consists of PS series or 3610 series straight stroke electric actuators and low flow resistance straight stroke sleeve valves (other brands of straight stroke actuators can also be matched). The electric actuator is an electronic integrated structure with a servo amplifier inside. It receives control signals and power from the regulating instrument (4-20mA DC, 0-10mA DC, or 1-5V DC) to control its operation and achieve automatic regulation and control of the process pipeline fluid. Used for precise control of process parameters such as pressure, flow rate, temperature, liquid level, etc. for gases, liquids, steam and other media, it is a universal control valve product that complies with IEC standards. Suitable for situations with large pressure difference and leakage, it has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. The control accuracy and performance are significantly improved compared to the DKZ model. Widely used in industries such as power, metallurgy, chemical, petroleum, environmental protection, light industry, and equipment.
Structural characteristics
The electric sleeve regulating valve is a pressure balancing type regulating valve, which adopts a sleeve guided, pressure balancing double sealing surface valve core mechanism, and is equipped with a multi spring pneumatic actuator or electric actuator. The flow channel is S-shaped and has characteristics such as balanced operation, large allowable pressure difference, precise flow characteristics, and low noise. Especially suitable for situations with high flow rate, large pressure difference before and after the valve, and no leakage requirements. This series of products comes in various forms, including room temperature, high temperature, low temperature, adjustable cutting, and corrugated pipe sealing. The nominal pressure rating of the product includes PN1.6, 4.0, 6.4, and 10.0; The valve body diameter range is DN20-300, suitable for various grades within the fluid temperature range of -196-+560 ℃. There are four levels of leakage: level IV, level V, and level VI. The flow characteristics include straight lines and equal percentage characteristics. Multiple varieties and specifications are available for selection.
