ZDLP electronic electric single-seated regulating valve is an industrial automation control valve composed of an electronic electric actuator and a high-precision single-seated globe-style valve body. This valve integrates advanced servo control technology and does not require an additional servo amplifier, as it can directly receive standard analog signals of 4-20mA DC or 1-5V DC from control systems (such as PLC, DCS). The actuator, through its built-in electronic module, efficiently converts electrical energy into linear displacement to drive the valve stem, causing precise movement of the valve plug relative to the seat. This adjusts the fluid flow area in real-time to achieve accurate control of process parameters like flow rate, pressure, temperature, and liquid level in the pipeline. Due to its single-seated plug structure, the valve features minimal leakage and high adjustment precision, making it a core execution unit for automation processes requiring tight control and high reliability.

1. Electronic integrated drive:Equipped with an integrated electronic electric actuator with a built-in servo system and position feedback module, significantly simplifying system wiring and reducing space requirements without an external control box.
2.Excellent sealing performance:The single-seated plug design with a precision-ground sealing surface ensures significantly lower leakage than double-seated or cage valves, reaching Class IV (metal seal) or Class VI (bubble-tight soft seal).
3.Diverse regulation characteristics:Valve plug shapes can be customized to provide equal percentage or linear flow characteristics, ensuring stable system control across various load changes.
4.Agile and precise response:The actuator features high resolution and a minimal dead zone, accurately capturing small signal fluctuations and executing valve position compensation instantly for low steady-state error.
5.Strong and stable driving force:The electric actuator provides high output thrust and features self-locking capabilities, effectively overcoming fluid disturbances and maintaining consistent valve position at the set point.
6.Intelligent safety protection:The actuator includes overload, stall, and over-temperature protection. In the event of signal interruption or power failure, it can execute logical protection based on preset safety positions (full open, full close, or fail-in-place).
7.Material and environmental adaptability:Body materials include cast steel, stainless steel, and special alloy steel, compatible with hot water, steam, oil, and various corrosive chemical media across petroleum, chemical, and power sectors.
8.Easy and economical maintenance:The simple structure with few internal parts allows for the inspection and replacement of the plug and seat without complex specialized tools or a pneumatic support system, resulting in low maintenance costs.
