GID electric high vacuum butterfly valve, this valve is suitable for non corrosive saturated water vapor, low vacuum pipeline, as a closed circuit equipment. The valve seal butterfly valve, 0.25MPa pressure sealing butterfly valve at both ends of the shaft seal, ensure that the shaft seal does not leak. The structure of the NKD941X-25C type double seat situation, two seat and the shaft are narrowed and rubber water pressure (pressure value 0.25MPa) combined with the situation of sealing. If necessary, electric heating assembly can be installed on the valve body.
