ZAZP Electric Compact Single-Seated Regulating ValveOverview

ZAZP electric compact single-seated regulating valve is an industrial automation control valve composed of a new generation of compact electronic linear actuators and a straight-through single-seated globe-style valve body. This product has undergone structural optimization based on traditional electric regulating valves, significantly reducing the overall height and weight (typically by more than 30%), making it more suitable for modern automated pipelines with limited space or strict load requirements. The valve receives standard analog signals of 4-20mA DC or 1-5V DC from control systems (such as PLC, DCS) and relies on the built-in servo amplification system to precisely control the linear displacement of the actuator, driving the valve plug to move accurately relative to the seat. Due to its single-seated sealing structure and precision-machined internal components, the valve features minimal leakage, extremely high adjustment precision, and rapid response, making it an ideal execution unit for automation control systems in fine chemicals, pharmaceuticals, food, and HVAC.

ZAZP Electric Compact Single-Seated Regulating ValveCharacteristic

1.Compact and lightweight design:The integrated structural design greatly reduces height and weight. This installation not only saves space but also significantly lightens the support pressure on the pipeline, facilitating layout in narrow or compact industrial environments.
2.Bubble-tight sealing:The single-seated plug design, combined with a precision-ground sealing surface, ensures exceptional shut-off performance. The sealing level can reach Class IV (metal-to-metal) or Class VI (bubble-tight soft seal), making it particularly suitable for conditions requiring strict internal leakage control.
3.High-precision regulation performance:The valve body flow path is an S-shaped equal cross-section, effectively reducing fluid resistance loss. The valve plug profile provides equal percentage or linear characteristics, ensuring smooth adjustment, small dead zones, and high repeatability for continuous proportional fine-tuning of fluid parameters.
4.Intelligent electronic drive system:Equipped with a high-performance electronic linear actuator with a built-in intelligent servo amplification module, eliminating the need for an external servo amplifier. It features self-diagnosis and self-calibration functions with strong anti-interference capability.
5.Large driving torque and self-locking:The actuator outputs strong thrust and possesses a natural mechanical self-locking function. In the event of power failure or signal loss, the valve remains in its current position, effectively preventing valve position drift caused by medium pressure fluctuations.
6.Comprehensive intelligent protection:The actuator features built-in electronic stroke limits, overload torque protection, over-temperature protection, and phase loss protection logic. It supports fail-safe pre-setting (full close, full open, or fail-in-place) during control signal failure.
7.Wide material adaptability:The valve body is available in cast steel (WCB), stainless steel (CF8/CF8M/CF3M), and high-temperature steel. Internal parts can be hardened or PTFE-lined, adapting to steam, water, oil, and various corrosive chemical media.
8.Convenient maintenance and low cost:The structure is simple with few internal parts. The top-pressed bonnet design allows for quick inspection and replacement of the valve plug, seat, and packing without removing the valve body, significantly reducing system maintenance expenses.
