Quality is everything! US Walker (WORK) imported electric vacuum butterfly valve is applicable to the vacuum system is turned on or off medium flow pipeline. Electric high vacuum butterfly valve transition back to electric, electronic adjustable valve drive, an external power supply can be switched (with manual transfer switch or computer control) or external input signal to achieve the valve opening and closing, or control in the middle position. Electric high vacuum valve can be mounted in any position. Electric high vacuum valve is suitable for working media air and non-corrosive gases. Electric high vacuum butterfly valve plate with clamp structure, the valve plate to the clamping ring, in addition to be used in a vacuum, can also be used at low pressure. Features: 1, the valve opening and closing electrical signal output, experts, dual power. 2, compact, light weight, easy to install. Small flow resistance, high turnover, easy operation. 3, choose a different materials, applicable to different levels of corrosive media. 4, simple and compact structure, small, lightweight, easy installation and maintenance, and can be installed in any position. 5.90 degree rotation, open and close rapidly, you can multi-position installation, the flow of influence from the media. 6, the use of electric devices 1/4 rotation, smooth and reliable, can be installed in any direction, the stem will not traverse. Description: Connection: clamp, ferrule, socket welding, butt welding, flanges, male, female.
