l ESD自立式截断系统用于井口或场站以及压力管道的保护装置，具有快速紧急关闭阀门的功能，能在设备超压或欠压时自动关闭。我公司生产的ESD自立式截断系统具有结构简单，体积小，安装方便，不易泄漏，可作为一个单阀直接安装在设备或管道上，无需额外的控制线路、能源，可节约大量成本。控制系统的所有零部件采用316不锈钢，抗腐蚀能力好，可长期在露天环境中使用。

l The ESD self-supporting cut-off system is used for wellhead or station and pressure pipeline protection devices. It has the function of quickly closing the valve quickly and can be automatically closed when the equipment is over or under pressure. The ESD self-supporting cut-off system produced by our company has a simple structure, small size, easy installation, and is not easy to leak. It can be installed directly on the equipment or pipeline as a single valve without additional control lines and energy, which can save a lot of costs. All the components of the control system are made of 316 stainless steel, which has good corrosion resistance and can be used in the open environment for a long time.

l ESD 自立式截断系统主要由主控中继阀、液控阀、高低导阀、减压器、溢流阀、蓄能器、液动执行机构、闸阀、不锈钢管、截止阀等组成。大量采用插装式结构设计，集成度更高，操作更方便，关闭更可靠的特点，采用 316 不锈钢制作，能适应各种恶劣的环境。在行业内属领先产品。

l ESD self-supporting shut-off system is mainly composed of main control relay valve, hydraulic control valve, high and low pilot valve, pressure reducer, overflow valve, accumulator, hydraulic actuator, gate valve, stainless steel pipe, globe valve, etc. A large number of plug-in structure designs are used, which have higher integration, more convenient operation and more reliable shutdown. They are made of 316 stainless steel and can adapt to various harsh environments. It is a leading product in the industry.
