Product Description

 Cryogenic High - Pressure Balanced Control Valve and Neles ND7000​

1. Product Overview​

The combination of Wuzhong Valve's Cryogenic and High - Pressure Balanced Control Valve and Neles ND7000 provides an efficient solution for industrial control. The former is specifically designed for harsh cryogenic and high - pressure environments, capable of precisely regulating fluid flow. The latter, as an intelligent valve positioner, can achieve accurate control of the valve. The two work in tandem to ensure the stable operation of the system.​

2. Product Features​

(1) Wuzhong Valve Cryogenic and High - Pressure Balanced Control Valve​
  1. Cryogenic and High - Pressure Resistance: Made of high - quality cryogenic steel and processed by special techniques, it can operate stably for a long time under cryogenic conditions of - 196℃ and ultra - high pressure (such as 42MPa), meeting the needs of industries such as LNG and air separation.​
  1. Balanced Structure: With a unique balanced valve core design, it can effectively offset the unbalanced force of the medium, reduce the thrust requirement of the actuator, make the valve action more sensitive, regulate the flow more accurately, and reduce energy consumption and equipment wear.​
  1. Low - Leakage Sealing: Using high - performance sealing materials and an optimized sealing structure, it ensures excellent sealing performance of the valve under cryogenic and high - pressure conditions. The leakage rate is much lower than the industry standard, ensuring system safety and preventing accidents caused by medium leakage.​
(2) Neles ND7000​
  1. High - Precision Positioning: Using advanced digital control technology, the valve positioning accuracy can reach ±0.1%, overcoming interference such as friction, ensuring the precise opening and closing of the valve, and improving the control accuracy and stability of the system.​
  1. Fast Response: It has an extremely short response time, can quickly capture changes in control signals, and drive the valve to act rapidly. It is suitable for industrial scenarios with high real - time requirements and can respond to changes in working conditions in a timely manner.​
  1. Intelligent Diagnosis and Maintenance: Equipped with an intelligent diagnostic module, it monitors the operating status of itself and the valve in real - time, automatically detects faults and alarms, and provides detailed fault information, facilitating maintenance personnel to quickly locate and solve problems, reducing downtime and maintenance costs.​
  1. Multi - Protocol Compatibility: It supports a variety of mainstream industrial communication protocols such as HART and Profibus - PA, and can be seamlessly integrated into various automation control systems to achieve remote monitoring, parameter setting, and diagnosis, facilitating the information management of factories.​

3. Application ​

  1. Liquefied Natural Gas (LNG) Industry: In LNG receiving terminals and liquefaction plants, it is used in links such as LNG transportation pipelines and liquid inlet and outlet of storage tanks to precisely control flow and pressure, ensuring the safe and efficient storage and transportation of LNG.​
  1. Air Separation Equipment: In the cryogenic liquid pipeline system of air separation units, this combination accurately regulates the flow of cryogenic media such as oxygen and nitrogen, ensuring the stability of the air separation process and producing high - purity gas products.​
  1. Petrochemical Cryogenic Processes: In petrochemical production occasions involving cryogenic and high - pressure reactions, separations, and other processes, such as the cold section of ethylene plants, it can reliably control process parameters and facilitate the smooth progress of production.​
