ZAZM electric compact cage guided control valve is an industrial automation control valve composed of a new generation of compact electronic electric actuators and cage-guided pressure-balanced valve bodies. The product adopts a compact structural optimization scheme. While maintaining high-performance regulation capabilities, its overall height and weight are reduced by more than 30% compared with traditional models. 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 drive the valve stem, moving the balanced valve plug within the cage axially. Due to the pressure balance hole design of the valve plug, most of the unbalanced force generated by the fluid is effectively offset, providing excellent dynamic operation stability and a large allowable pressure differential. The ZAZM model integrates flow control, pressure regulation, and noise reduction performance, making it an ideal choice for industries such as petroleum, chemical, pharmaceutical, and energy to handle high pressure differentials and conditions with strict requirements for control precision.

Feature

1. Compact structural design:The valve body and actuator adopt a lightweight and integrated design, featuring small installation space and light weight. This significantly reduces the strength requirements for the pipeline support system and is particularly suitable for compact modular pipeline layouts.
2.Pressure-balanced valve plug structure:The valve plug is equipped with special balance holes to offset the unbalanced force of the medium acting on the plug in real-time. This feature allows the actuator to achieve stable control of high-pressure differential fluids with minimal thrust.
3.Excellent dynamic stability:Utilizing cage side-guiding technology, the large and precise guiding area effectively suppresses vibration and high-frequency whistling caused by medium erosion during the opening process, ensuring stable and reliable operation.
4.Superior noise and cavitation resistance:The flow path design of the cage window effectively changes the fluid velocity distribution, providing pressure reduction and energy dissipation. This significantly reduces operating noise and improves the service life of the valve under harsh conditions.
5.High-precision intelligent drive:Equipped with a high-performance electronic linear actuator with a built-in intelligent servo circuit. It features automatic calibration, zero/full-scale fine-tuning, and fault self-diagnosis functions with high adjustment sensitivity.
6.Reliable sealing performance:Available in various sealing forms, including metal hard seal (Class IV) and soft seal (Class VI/bubble-tight). The sealing surface material is reinforced for erosion and wear resistance.
7.Comprehensive safety protection:The actuator features overload protection, stall alarm, and stroke limit functions. It supports fail-safe pre-setting (full open, full close, or fail-in-place) upon control signal interruption to ensure system safety.
8.Modular rapid maintenance:Adopting a top-entry assembly and disassembly structure. During internal cleaning or replacement of wearing parts (such as cages and seals), there is no need to remove the valve body from the pipeline, greatly improving maintenance efficiency.
