磅级电动截止阀

磅级电动截止阀是采用磅级（Class）压力标准设计的自动化控制阀门，核心用于石油、化工、电力等工业系统的中高压管路，实现对蒸汽、油品、腐蚀性流体的精准截止与流量调节，尤其适配需远程或自动控制的场景。

磅级电动截止阀阀门磅级范围覆盖Class 150至Class 2500，对应不同压力需求，工作温度根据材质差异可达-196℃-538℃，适配低温至高温的复杂工况。阀体多选用铸钢、不锈钢或合金钢，抗冲击与耐腐蚀性能好；阀芯采用精密研磨工艺，配合金属硬密封或软密封结构，兼具高密封稳定性与长使用寿命。驱动方式为电动执行器（多为开关型或调节型），可通过PLC、DCS系统实现远程控制，支持信号反馈功能，能实时监控阀门开关状态；连接方式以法兰连接为主，符合ANSI、ASME等标准，安装兼容性强，广泛应用于炼油厂、火力发电厂、化工装置的关键管路，满足自动化生产中高精度、高稳定性的流体控制需求。

Pound-Class Electric Globe Valve - Product Overview

The pound-class (Class) electric globe valve is an automatic control valve designed in accordance with the pound-class pressure standard. It is mainly used in medium high-pressure pipelines of industrial systems such as petroleum, chemical industry, electric power to achieve precise shut-off flow regulation of steam, oil products, corrosive fluids, especially suitable for scenarios requiring remote automatic control.

This type of valve has a pound-class range Class 150 to Class 2500, corresponding to different pressure requirements. The operating temperature can reach -196℃-538℃ depending on material differences, adapting to complex working conditions low temperature to high temperature. The valve body is mostly made of cast steel, stainless steel, alloy steel, with excellent impact resistance corrosion resistance; the valve core adopts a precision grinding process, combined with a metal hard-seal soft-seal structure, which has both high sealing reliability long service life. The driving method is an electric actuator (mostly on-off type regulating type), which can realize remote control through PLC DCS systems, support signal feedback function, monitor the valve switch status in real time. The connection method is mainly flange connection, which complies with international standards such as ANSI ASME, with strong installation compatibility. It is widely used in key pipelines of refineries, thermal power plants, chemical plants to meet the high-precision high-stability fluid control needs in automated production.
