The perfect partner for industrial fluid control — Wuzhong Instrument ABM + Samson 3730-3 combination

Product Description

The powerful combination of Wuzhong Instrument ABM Low-Temperature Large-Diameter Pressure-Balanced Cage Control Valve and Samson 3730-3 Digital Electro-Pneumatic Valve Positioner is specifically designed for extreme low-temperature and harsh working conditions. The ABM control valve adopts a pressure-balanced cage structure. The valve body is available in materials such as carbon steel and low-temperature stainless steel. The bonnet comes in standard type, finned type, and extended type, enabling stable operation in an ultra-low temperature environment of -196℃ to a high temperature of 530℃. The nominal diameter ranges from DN80 to DN400, meeting the requirements of large-flow control. The paired Samson 3730-3 positioner precisely drives the actuator of the control valve by receiving a 4-20mA electrical signal, achieving accurate adjustment of the valve opening. It supports multiple communication protocols such as HART and Profibus, facilitating remote monitoring and parameter setting.
Product Features
1. Adaptability to Extreme Conditions: The ABM control valve has passed the liquid nitrogen immersion test, meeting the application requirements of the -196℃ ultra-low temperature environment and featuring excellent protection. The Samson 3730-3 positioner has good environmental tolerance. The combination of the two can operate stably under harsh conditions such as high temperature, low temperature, humidity, and dust.
1. High-Precision Control: The Samson 3730-3 positioner is equipped with advanced control algorithms. Combined with the pressure-balanced design of the ABM control valve, the positioning accuracy can reach ±0.5%, ensuring precise control of parameters such as fluid flow and pressure and effectively reducing system fluctuations.
1. Efficient Diagnosis and Maintenance: The Samson 3730-3 supports self-diagnosis function, which can monitor the valve operation status in real-time and give early warnings of abnormalities. The modular design of the ABM control valve facilitates disassembly and maintenance. The combination of the two greatly improves equipment maintenance efficiency and reduces downtime.
1. Flexible Communication Integration: It supports multiple communication protocols and can be seamlessly integrated into control systems such as DCS and PLC, enabling remote operation and data interaction to meet the needs of modern industrial automation management.
Application Scenarios
1. LNG Industry Chain: In the LNG liquefaction, storage, and transportation processes, it is used for the control of LNG storage tank liquid inlet and outlet and the adjustment of vaporizer inlet and outlet, ensuring the stable and safe transportation of low-temperature media.
1. Air Separation Equipment: It precisely regulates the flow and pressure of low-temperature fluid pipelines such as liquid oxygen, liquid nitrogen, and liquid argon in air separation units, ensuring the efficient operation of the gas separation process.
1. Petrochemical Industry: It is suitable for processes such as atmospheric and vacuum distillation in refineries, hydrogenation units, and ethylene cracking. It can achieve precise fluid control under high-pressure difference and high-flow rate conditions, improving production efficiency and product quality.
