Note: 1, the hand wheel, handle and drive mechanism for lifting are not allowed to use, valve prices, and forbid the collision. 2, Gate Valve should be mounted vertically (ie stem in a vertical position, the hand wheel at the top). 3. With a bypass valve to open the bypass valve opening should be preceded (in order to balance imports and exports and reduce the pressure opening force). 4, with the valve drive mechanism, according to the provisions of product installation instructions. 5, if the valve switch is used frequently, lubrication at least once a month. Advantages: 1, the medium can flow in any direction to the sides, easy to install. Both sides of the valve channel is symmetrical. 2, the structure length (the distance between two connection lines between the end face of the housing) is small. 3, simple shape, structure, length short, stainless steel valve manufacturers, good manufacturing processes, a wide range. 4, compact structure, the valve rigid, channel flow, flow resistance small number, the sealing surface of stainless steel and tungsten carbide, valves, long service life, the use of PTFE packing. Reliable sealing. Lightweight and flexible operation. Gate (gate valve) is a shutter opening and closing pieces, the direction of movement of the fluid direction perpendicular to the gate, the gate valve can only be fully open and fully closed, valve type, does not apply to the door parameters vary, usually 5 °, medium temperature not high when 2 ° 52 '. Improve its process of, to make up the sealing surface angle deviations arising during processing, this gate is called the flexible gate. Valve Co., Ltd. Shandong Everbright production of such types of valves wide range of applications, reliable, no leakage, leakage phenomenon, frequent switching is not stuck, rusted, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing, the best choice for food factory. _ _ Valve Valve Type Valve Shandong Everbright Ltd. Shandong Everbright provided by the valve. Shandong Everbright Valve Co., Ltd. (www.sdgdfm.com) strong, credible, Shandong Weifang ball industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Everbright valve into the brilliant and you work for a better future!
