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 the need for an external servo amplifier.
2.Excellent sealing performance:The single-seated globe-style plug design with a precision-ground sealing surface ensures extremely low leakage. Its leakage standards are far superior to double-seated or cage valves, reaching Class IV (metal seal) or Class VI (bubble-tight soft seal).
3.High adjustment precision and stability:The single-seat structure provides a simple flow path with relatively low fluid disturbance. Combined with the precision valve plug profile design, it offers equal percentage or linear regulation characteristics, ensuring stable flow control under various load conditions.
4.Agile and precise response:The actuator features high resolution and a minimal dead zone, accurately capturing small signal fluctuations (e.g., 4-20mA) and executing valve position compensation instantly to ensure timely dynamic response and minimal steady-state error.
5.Compact with high shut-off force:Although the single-seated valve does not have a balanced structure, within the rated pressure differential range, the downward thrust generated by the actuator ensures tight contact between the plug and seat, providing a high shut-off ratio for process integrity.
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 various special alloy steels, compatible with hot/cold water, low-pressure steam, oil, and various corrosive chemical media across petroleum, chemical, and pharmaceutical sectors.
8.Easy maintenance and low cost:The structural design is simple with few internal parts. During maintenance, the disassembly and replacement of the valve plug and seat do not require complex specialized tools. Online maintenance is convenient, significantly shortening downtime and reducing costs.
