一、进口气动内螺纹球阀概述

进口气动内螺纹球阀（美国威盾VTON），Pneumatic thread ball valve，气动不锈钢螺纹球阀，气动不锈钢丝扣球阀，气动不锈钢小口径球阀，是由内螺纹球阀和气动执行器组成，有气源推动执行器来控制球阀的开关或者调节的球阀。

Pneumatic threaded ball valve (VTON), pneumatic threaded ball valve, pneumatic stainless steel threaded ball valve, pneumatic stainless steel threaded ball valve, pneumatic stainless steel small diameter ball valve, is a ball valve composed of an internal threaded ball valve and a pneumatic actuator, which is driven by an air source to control the opening or adjustment of the ball valve.

二、进口气动内螺纹球阀特征

1、气动球阀及对焊连接球阀分为整体式、两段式及三段式。

2、阀体铸造采用美国威盾VTON的先进工艺，结构合理、造型美观。阀座采用弹性密封结构，密封可靠，启闭轻松。

3、阀杆采用有倒密封的下装式结构，阀腔异常升压时，阀杆不会被冲击。可设置90°开关定位机构，根据需要加锁以防止误操作。

4、进口气动内螺纹球阀适用于PN1.0～4.0MPa,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，用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氨盐水、中和水等多种介质。

1. Pneumatic ball valves and butt welded ball valves are divided into integral, two-stage, and three-stage types.

2. The valve body casting adopts the advanced technology of American Weidun VTON, with a reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, with reliable sealing and easy opening and closing.

3. The valve stem adopts a bottom mounted structure with inverted sealing, and when the valve chamber is abnormally pressurized, the valve stem will not be impacted. A 90 ° switch positioning mechanism can be set, and locks can be added as needed to prevent accidental operation.

4. The imported pneumatic internal thread ball valve is suitable for various pipelines with PN1.0-4.0 MPa, working temperature of -29-180 ℃ (with reinforced polytetrafluoroethylene as the sealing ring) or -29-300 ℃ (with aligned polystyrene as the sealing ring). It is used to cut off or connect the medium in the pipeline, and different materials are selected. It can be classified as suitable for various media such as water, steam, oil, nitric acid, acetic acid, ammonium salt water, and neutralized water.
