DK941X Vacuum Butterfly Valve
Product number:DK941X
product description:

  This valve is suitable for non-corrosive saturated steam low vacuum pipelines as a closed circuit device.This series of valve-sealed butterfly valves are sealed with 0.25MPa pressure at the shaft seals at both ends of the butterfly valve to ensure that there is no leakage at the shaft seal. The structure of DS9D41X-2.5C is a double-seat form, and the seal between the two seats and at the shaft end is a combination of rubber slits and pressure water (pressure value 0.25MPa).If the user needs, an electric heating device can be installed on the valve body.
