一、进口气动真空球阀概述

进口气动真空球阀（美国威盾VTON），Pneumatic vacuum ball valves，也叫高真空(压力)气动球阀，切断负压球阀，是指气动高真空(压力)球阀是通过电磁换向阀改变气路方向，控制执行气缸来驱动球阀，达到接通或切断真空(压力)系统管道路中的介质流。应用于真空、乳制品、酒业、生物工程、食品、制药、饮料、化妆品及化工领域。可选配反馈信号装置及电气阀门定位器。

美国威盾VTON进口气动真空球阀主要产品有气动真空法兰球阀，气动真空螺纹球阀，气动真空活套法兰球阀，广泛应用于真空、乳制品、酒业、生物工程、食品、制药、饮料、化妆品及化工领域。

Pneumatic vacuum ball valves (VTON), also known as high vacuum (pressure) pneumatic ball valves or negative pressure cut-off ball valves, refer to pneumatic high vacuum (pressure) ball valves that change the direction of the air path through an electromagnetic directional valve, control the actuator cylinder to drive the ball valve, and achieve the purpose of connecting or cutting off the medium flow in the vacuum (pressure) system pipeline. Applied in vacuum, dairy products, wine industry, biotechnology, food, pharmaceuticals, beverages, cosmetics, and chemical industries. Optional feedback signal device and electrical valve locator.

The main products of VTON imported pneumatic vacuum ball valves from the United States include pneumatic vacuum flange ball valves, pneumatic vacuum threaded ball valves, and pneumatic vacuum looping flange ball valves, which are widely used in vacuum, dairy products, wine industry, biotechnology, food, pharmaceuticals, beverages, cosmetics, and chemical industries.

二、进口气动真空球阀产品特点

（1）、密封结构设计独特漏率可达到＜1×10-10Pa.M3/S,改变了球阀不能满足高真空、超高真空的现状；

（2）、开关扭矩小,配置气动执行器小，工作稳定，可靠；

（3）、结构紧凑,重量轻,外形简洁、美观；

（4）、真空球阀既能适用高真空又能适用一定的正压力下使用。由于球阀全通导又能达到超高真空要求,所以气动真空球阀也能适用于加速器真空系统。
