Only clear specifications, type, working pressure of pneumatic valve procurement practices to meet the procurement requirements in the current economic environment, market is imperfect. Because the pneumatic valve manufacturers under competitive products for the respective pneumatic valves are unified design concept, with different innovations, they formed their own company standards and product personality. Therefore, when the pneumatic valve procurement more detailed technical requirements, coordinating with manufacturers to reach a consensus, as an annex to the pneumatic valve procurement contract is necessary. The upper portion of the hand wheel overhanging rise and fall of the indicator rod valve, the valve gate is marked in a raised state or degraded state. Stainless Valve closed valve, outrigger indicator lever at the lowest position; on the contrary, when the valve fully open, extended indicator lever in the highest position. Namely, the state of the scene based valve opening and closing instructions. 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. Consistent shift gearbox 3.1 external enclosure materials and corrosion requirements and body principles. 3.2 Measures should be sealed box after box assembly can withstand immersion three meters of water conditions. Weifang valve opening and closing stopper 3.3 box on the adjustment nut should be in cabinets or located outside the box, but special tools need to work. 3.4 Drive structural design reasonable temperature and pressure valves, open and close valves can only drive shaft rotation, as not to traverse up and down, bite moderate transmission parts, does not produce open and close with a load when the separation skid. 3.5 Transmission Box Office with the valve shaft seal leak can not be connected to the whole, or else there should be a reliable anti-leakage measures strings. 3.6 cabinets without debris, grease should be protection gear meshing.
