DK941X vacuum butterfly valve DK941X vacuum butterfly valve product overview: First, the vacuum butterfly valve is suitable for non-corrosive saturated water steam low vacuum pipe road, as a closed circuit equipment. This series of valve seal type butterfly valve, butterfly valve at both ends of the shaft seal with 0.25MPa pressure seal to ensure that the shaft seal does not leak. DS9D41X-2.5C is a double seat structure, and the rubber slits between the two and the end of the shaft are sealed with pressure water (pressure value 0.25MPa). If the user needs, the valve body can be closed with an electric heating device. Second, the main parameter model DS9D41X-2.5CDS9D41X-2.5C Nominal pressure (MPa)0.250.25
