一、进口内螺纹电动球阀产品概述

美国威盾VTON内螺纹电动球阀是由威盾的电动执行器和内螺纹的一片式，两片式，或者三片式球阀组成，由于DN15-50的小口径的管道的介质的控制单元。

内螺纹适用于PN1.0～10.0MPa，工作温度-29～180℃(密封圈为增强聚四氟乙烯)或-29～300℃(密封圈为对位聚苯)的各种管路上，内螺纹电动球阀用于两位切断、调节的场合。用于截断或接通管路中的介质。电动执行机构内置伺服系统，无须另配伺服放大器，输入4-20mA信号220VAC电源即可运转。电动内螺纹球阀具有连线简单，结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。内螺纹电动球阀可分为：三片式电动球阀、焊接式电动球阀、卡箍式电动球阀。可分别适用于水、蒸汽、油品、硝酸、醋酸等多种介质。

VTON internal thread electric ball valve is composed of Weidun's electric actuator and one piece, two piece, or three piece internal thread ball valves. It is used as the control unit for medium in small diameter pipes with DN15-50 diameter.

Internal thread is suitable for various pipelines with PN1.0~10.0MPa, working temperature of -29~180 ℃ (with reinforced polytetrafluoroethylene as the sealing ring) or -29~300 ℃ (with aligned polystyrene as the sealing ring). Internal thread electric ball valves are used in situations where two positions are cut off and adjusted. Used to cut off or connect media in pipelines. The electric actuator is equipped with a built-in servo system, without the need for an additional servo amplifier. It can operate with a 4-20mA signal and a 220VAC power supply. Electric internal threaded ball valves have the advantages of simple connection, compact structure, small size, light weight, low resistance, and stable and reliable operation. Internal threaded electric ball valves can be divided into three types: three piece electric ball valves, welded electric ball valves, and clamp electric ball valves. It can be applied to various media such as water, steam, oil, nitric acid, acetic acid, etc.
