The NDIV Rising Stem Ball Valve has involved in National Energy Bureau And China National Petroleum Corporation “Oil And Gas Pipe Key Equipment Localizing Manufacturing Project”.
The NDIV Rising Stem Ball Valve Main Technical Parameter Meet The Overseas Made Same Kind Product
---Verify By Oil And Gas Pipe Key Equipment Localizing Manufacturing Project
The NDIV rising stem ball valve utilize the interaction of the sloping surface on the bottom of the stem and spiral groove for the core tilting and rotation. When valve begins to opening,the core tilt away from the seat,the line flow passes uniformly around the core face, which reduced the seat wear and erosion from high velocity flow, the core then rotates to the fully open position.In the close position, the angled flat surface on the lower stem to mechanically wedge the core tightly against the seat,and generate a needed sealing pressure to ensure the reliable sealing.
