A gate valve is a type of valve that uses a gate or wedge-shaped disc to stop or start the flow of a fluid. The gate is attached to a stem that is operated by a handle or a wheel, and it can be raised or lowered to open or close the valve. When the gate is fully raised, it allows the fluid to flow freely through the valve. When the gate is fully lowered, it blocks the flow of the fluid. Gate valves are widely used in a variety of applications, including oil and gas, chemical processing, water treatment, and power generation. They are available in a range of sizes and materials to suit different applications and fluid types. In China, gate valves are commonly used in industrial piping systems and are designed to meet Chinese national and industry standards. They are known for their reliability, durability, and ease of use, and they are often used in applications where a tight seal is required to prevent leaks. Like JIS flanged ball valves, gate valves are typically connected to the rest of the piping system using flanges, which are fastened together with bolts or other fasteners. The valve body of the gate valve can be made of metal. Such as: forged steel gate valve, stainless steel gate valve, alloy gate valve, bronze gate valve, cast steel gate valve, carbon steel gate valve, etc. Among them, forged steel gate valves are widely used, especially as a cut-off device when the size is greater than 50mm. The main body can also be made of non-metallic materials. For example, ceramic gate valves have good wear resistance and hardness. Some other gate valves are made of special materials, such as Hastelloy gate valves, special steel gate valves and special alloy gate valves. To transport and process strong corrosive media, duplex stainless steel gate valves or super stainless steel gate valves are usually used to alleviate the problem, because they can work well in areas with corrosive environments.
Metal Seated Lift Plug Valve, ASTM A351-CF8, CF8M, CF3, CF3M Plug valves are valves with round or conically tapered "plugs" which may be rotated within the valve body to manage flow with the valve. The plugs in plug valves have a number of hollow passageways going sideways with the plug, to ensure that fluid can flow with the plug once the valve is open. Plug valves are pretty straight forward and frequently economical. Metal Seal Lift Plug Valve Overview Metal Seated Lift Plug Valve is relevant towards the cutting and connection of pipelines medium that turned on in a variety of industries as oil, chemical industry, pharmacy, chemical fertilizer, power industry etc. under nominal pressure of CLASS150-1500 LbsS, and dealing temperature of -29~550�°C. a. The merchandise has reasonable structure, reliable sealing, excellent performance and delightful appearance. b. Frequent lowering and raising from the valve is transported out as the sealed surface is removed so it won't cause abrasion around the sealed surface. c. The Plug valves's characteristic double-direction flow makes installation and employ easier. d. The types of materials from the parts and dimensions of flanges could be reasonably configured according the particular operation condition from the needs from the clients, in order to satisfy the various needs of engineering. When the lift plug valve comes to procedure for frequent lowering and raising from the valve, when opening the valve, to begin with, turn the hands wheel to help make the plug lifted and separated using the sealed surface, then turn the handle by 900 to help make the funnel of plug towards the funnel of valve body, so the valve is opened up when closing the valve, to begin with, turn the handle by 900 to help make the funnel of plug vertical towards the funnel of valve body, after which turn the hands wheel to descend the plug, so the valve is closed.

DIN soft seal non-rising gate valve Product Name: DIN soft seal non-rising gate valve Model No.:(DIN)F4Z45X-16Q-100 Brief introduction: Gate valve is one of the widely used industrial valves in fluid transport projects. For traditional gate valves, there are some weaknesses, like fluid leakage, internal corrosion,etc. This resilient soft seal gate valve adopts the novel structure design, strict manufacturing technology, and new materials, which overcomes the defects of traditional gate valves and has reliable sealing performance, long service life, and is easy and convenient to operate and maintain. Characteristics of Soft seal gate valves: 1. overall rubber coated. Ductile iron gate valve has characteristics of overall rubber coated, great sealing Performance, accurate physical dimensions, which can guarantee the zero leakage, long service life, and small flow resistance. 2. light weight. The valve body and valve deck are made of ductile iron, which is light in weight, safe and reliable, easy to install. 3. corrosion resistant. The inside of the valve body is coated with non-toxic epoxy resin, which is anti-corrosive and rust resistant. That kind of gate valve not only can be used for drinking water piping line systems, also can be used for wast water delivery pipe line systems. 4. Triple seal.
