DKZ941HElectric vacuum gate valveProduct Description:

DKZ941H、DKZ941Y Type PN10~PN100 Steel Vacuum Gate Valve: Electric, Flanged, Clear Stem Wedge Type Rigid Single Gate Plate, Sealing Surface Material of Valve Seat: Alloy SteelDKZ941HHardened AlloyDKZ941YNominal Pressure PN10~PN100Valve body material isCarbon SteelDKZ941H)、Chromium-Molybdenum SteelDKZ941YVacuum Check Valve Vacuum Gate ValveDK/ZConnection types include flanged and welded, with driving methods available in manual and electric. This vacuum isolation valve is suitable for working temperatures≤425℃ and≤550Used as an opening and closing device on pipelines with working mediums such as water, steam, oil, and non-corrosive gases; particularly suitable for the condensation and vacuum negative pressure systems of thermal power plant turbines, serving as a vacuum isolation and sealing function. 

The vacuum globe valve has a plug as its opening and closing element. The motion direction of the plug is perpendicular to the fluid direction, and the globe valve can only be fully open or fully closed. , Cannot be adjusted or throttled. The product enjoys certain price and technical advantages in the industry. The gate valve has two sealing surfaces., MoreTwo sealing surfaces of the commonly used pattern gate valves form a wedge shape, with the wedge angle varying with the valve parameters. , Generally speaking 5℃, Medium temperature is not high when 2°52＇ The gate of a wedge gate valve can be made into a single piece A rigid gate plate; or a gate plate that can produce a slight deformation , Improve its processability , Compensate for the deviation in sealing surface angle during the machining process ,This type of gate is called an elastic gate. The valve is generally installed horizontally. This vacuum isolation gate valve is suitable for operating temperatures≤425℃ and≤550Used as an opening and closing device on pipelines carrying water, steam, oil products, and non-corrosive gases; especially suitable for the condensation and vacuum negative pressure systems in thermal power plants, serving as a vacuum isolation seal.
