一、进口电动法兰球阀产品概述

美国威盾VTON的电动法兰球阀只需要旋转90°即可全关全开。阀体通道和连接管径相等并成一直径，介质几乎可以毫无损失的流过。电动法兰球阀适用于两位切断、调节的场合。主要分为两大类：电动软密封球阀和电动硬密封球阀，电动软密封球阀主要适用于温度低于250度以内的介质。

电动法兰球阀主要适用于250度以上的介质。该阀密封性能优良、流通能力大、装卸维护方便、流阻小、密封可靠，甚至切断。电动法兰球阀体积小、重量轻、推力大、功能强、伺服放大器内装、操作方便、可靠性高，球阀与执行器采用直连方式，内置伺服系统，无须另配伺服放大器，输入输出信号4-20mA及220VAC电源即可控制运转。电动法兰球阀具有连线简单、结构紧凑、动作稳定可靠等优点。电动法兰球阀是一种重要的电动阀门类，在石油化工和长输管线等领域有广泛应用。它的关闭件是一个带孔的部分球体，球体随阀杆转动，实现阀门的开启或关闭。电动法兰球阀可实现对石油、化工、造纸、冶金、污水处理、油罐车等运输管道内介质的切断和流通。

VTON's electric flange ball valve only needs to be rotated 90 ° to fully close and fully open. The valve body channel and the connecting pipe have the same diameter, and the medium can flow almost without any loss. Electric flange ball valves are suitable for two-point cutting and adjustment situations. It is mainly divided into two categories: electric soft sealed ball valves and electric hard sealed ball valves. Electric soft sealed ball valves are mainly suitable for media with temperatures below 250 degrees.

Electric flange ball valves are mainly suitable for media above 250 degrees. The valve has excellent sealing performance, large flow capacity, convenient loading and unloading maintenance, low flow resistance, reliable sealing, and even cut-off. The electric flange ball valve has small volume, light weight, high thrust, strong function, built-in servo amplifier, easy operation, and high reliability. The ball valve and actuator are directly connected, with a built-in servo system, without the need for an additional servo amplifier. The input and output signals can be controlled by 4-20mA and 220VAC power supply. Electric flange ball valves have the advantages of simple connection, compact structure, stable and reliable operation. Electric flange ball valve is an important type of electric valve, widely used in fields such as petrochemicals and long-distance pipelines. Its closing component is a partially spherical body with a hole, which rotates with the valve stem to achieve the opening or closing of the valve. Electric flange ball valves can achieve the cutting and circulation of media in transportation pipelines such as petroleum, chemical, papermaking, metallurgy, sewage treatment, and oil tank trucks.
