Vacuum Butterfly Valve

Vacuum Butterfly Valve

Product Overview

Pneumatic vacuum butterfly valve GIQ is composed of angle-stroke pneumatic actuator and butterfly valve body. GIQ pneumatic vacuum butterfly valve is used to connect or cut off the airflow in the vacuum pipeline by changing the direction of the air path through the solenoid reversing valve and controlling the actuating cylinder to drive the butterfly valve for opening and closing motion. Pneumatic vacuum butterfly valve is applicable The medium is pure air and non-corrosive gas, optional feedback signal device and electrical valve positioner. The pneumatic high altitude true butterfly valve is powered by compressed air, changing the direction of the air path through the pneumatic device, controlling the actuating cylinder to drive the butterfly valve to connect or cut off the airflow in the vacuum pipeline. The applicable working medium is air and non-corrosive gas.

product features

Pneumatic vacuum butterfly valve usually connects the flange with sealing groove to a section that is in vacuum for a long time, while the other side of the flange is connected to the side of the frequent amplifier, positive use of the butterfly valve, which is conducive to increasing the sealing force of the valve plate. Vacuum sealing connection can be divided into static sealing and dynamic sealing. When the pneumatic high vacuum butterfly valve is connected with flexible seal in the vacuum rubber, it is a thick-walled tube made of vacuum rubber with smaller outgassing volume; it is mostly used in the entrance of mechanical vacuum pump with caliber less than 50mm to connect with the pipeline being pumped, so as to reduce the impact of vibration on the vacuum system when the mechanical pump is working. Of course, it can also be used for connecting glass tubes, metal tubes and other related components. The connection between the rubber hose and the connected parts is realized by means of special fittings.

Zhejiang Huachi Co., LTD  vacuum butterfly valve is widely used in building materials, metallurgy, mining, electric power and other production processes medium temperature≤300℃nominal pressure of 0.1Mpa pipeline, used to connect, open and close or adjust the amount of media.
