All welded ball valves are widely used in city gas,urban heating,petrochemical,shipbuilding,steel,pressure regulating stations,power plants and other types of pipeline equipment.
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
Fluorine linde adjusting valves widely used in acid, alkali and other strong corrosive media and toxic, volatile, permeable and other gas, liquid media control.
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
Product introduction: Vacuum welding gate valve is a kind of mechanical equipment, which is suitable for pipelines with working temperature ≤ 425 ℃ and ≤ 550 ℃ and working medium of water, steam or air.
Brief introduction of insulation valve structure: Insulation valves are welded with a metal jacket on the valve body. Steam, heat-conducting oil, cooling water, air-conditioning, etc. are injected into the metal jacket so that the medium of the valve body can meet the requirements under the conditions of normal temperature, heating, and cooling.
