一、活套法兰电动真空(压力)球阀概述

GUD型系列电动真空(压力)球阀采用回转型电动、电子调节式阀门驱动装置，可以通过外接电源的切换(用手动转位开关或电脑控制)或外部输入信号，来实现阀门开、关或中间位置的控制，从而达到接通或切断真空管路中气流的目的。阀门为直通式，靠球面密封，因而既能用在真空状态下，也能在低压状态下使用，并可任意位置安装。

适用的工作介质为带酸、碱性的气体或液体。

The GUD series electric vacuum (pressure) ball valve adopts a rotary electric and electronic regulating valve driving device. It can be controlled to open, close or intermediate position of the valve through external power switching (manually operated by a rotary switch or computer control) or external input signals, thereby achieving the purpose of connecting or cutting off the airflow in the vacuum pipeline. The valve is a straight through type with a spherical seal, which can be used in both vacuum and low-pressure conditions, and can be installed in any position.

The suitable working medium is gas or liquid with acidic or alkaline properties.
