Has the world's highest technical level and to fill the gaps in the domestic anti-high sulfur special high-acid plate valve ?? CL150LB, high pressure CL900-2500LB-DN25-500 flat gate valve, has been successfully developed. At present, the product has been successfully used in the main Puguang Gas Field in China to develop ground transportation projects in the yard. It is understood that the product has the advantages of small flow resistance, large flow capacity, and clear cleaner, and has the advantages of light weight and easy opening and closing. It can be widely used in the production and transportation of sulfur-containing oil and natural gas, oil and gas pipeline, Refinery and other conditions, as a control medium circulation and closing of the hoist device. According to the needs of the project, the valve manual, bevel gear drive, explosion-proof electric drive and other means. The valve is also designed with the valve position switch instructions, stem protection cover, to prevent misuse of the protection lock, etc., to ensure the safe operation of the valve, the control valve to avoid misuse. The product uses a single gate hard seal, floating patented valve seat, to ensure that debris will not enter the back of the seat, with fire and anti-static function, the valve rough casting for the company smelting, casting. Special structure of the patented flexible fire valve seat, to overcome the limitations of the past can only be used O-ring, the elastic valve seat plate gate valve applications extended to the field of high temperature and high pressure. Flat gate valve features: 1, fully enclosed structure, good protective performance, can adapt to all-weather requirements 2, the flat gate valve automatically closed off when the cavity high pressure to ensure safe use 3, at full open, the channel is smooth to a straight line, flow resistance Coefficient is very small, no pressure loss, can pass the hair ball cleaning pipeline 4, seat with O-ring seal and preload force of the floating valve seat structure, so that the two-way flat gate valve import and export seal; and the structure of the opening and closing torque Only ordinary valve 1/2, can easily open, close the Qin valve 5, with a self-sealing packing structure, without frequent adjustment, open, off extremely light, and the sealing *, stuffing box with Auxiliary seal grease injection structure, the sealing performance is absolutely *, truly zero leakage; Solve the common valve packing at the most easy to leak the drawbacks
AWWA Flange Standards differ from ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers) certifications in a variety of ways, the most important being their specificity: AWWA standards evaluate properties that particularly affect potable water use, as opposed to broader industrial flange applications.
