Valve purpose: Eccentric hemisphere valve, also known as C-type ball valve, is to make the valve unblocked or blocked by rotating the hemisphere. The switch is light and small in size. It can be made into a large diameter. It has reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often close1
Product use: VQ347H,VQ647H and VQ947H adjust v-ball valve, because the ball core has V-shaped structure, it has shear effect on the valve seat. Therefore, it is suitable for the control of the relevant process parameters in the suspension medium containing fiber or small solid particles in the industrial enterprises such as papermaking, chemical in1
ANSI ball valve and flange gate valve is the same type of valve, the difference is that its closing part is a ball, the ball around the center line of the valve body for rotation to open and close a valve.Ball valve in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium.Two-piece ball valve, three-piece 1
