- Q: Role of ball valve DN20-Q11F-16
- Type Q - 1 - connection form: threaded connection1 - gate structure: single gateF: PTFE sealing materialsDN - nominal diameter mm 2016 pressure rating: 161.6MPaQ11F ball valve is to control the circulation and cut-off of the pipeline medium.
- Q: Copper ball Q11F-20T is what mean?
- Q ball valve1 internal thread1 throughF PTFE soft seal20=20PA=2.0mpa pressureT copper material
- Q: PPR ball valve which face is open, which face is closed, there is a o, there is a s, which is off, ah, which is open, well intentioned people told me that the original finished by forget
- Hello, I am glad to answer for you. O is on, s is off. I hope I can help you.
- Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?
- Stop valve: a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very cooperative for cutting or regulating and throttling.Advantages: in the process of opening and closing, because the friction between the valve and the sealing surface of the valve body is smaller than that of the gate valve, the utility model has the advantages of wear resistance. Second, the opening height is generally only 1/4 of the seat channel; therefore, it is much smaller than the gate valve; usually there is only one sealing surface on the valve body and the disc; therefore, the manufacturing process is better and the service is easy to maintain. Because its packing is generally a mixture of asbestos and graphite, it has a higher temperature resistance. Steam valves are normally used with stop valves.Disadvantages: as a result of the medium through the valve flow direction has changed, so the minimum flow resistance valve is higher than most other types of valves; second, due to longer travel, opening slower than the ball.
- Q: Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball
- There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.
- Q: What does W represent in copper ball valve Q11W-16T?
- Valve sealing materials are all valves of the body material, sealing surface material code with "W" said
- Q: What is the difference between ball valve and butterfly valve?
- The ball valve and butterfly valve butterfly valve ball valve and the maximum difference between the difference between the two is the valve opening and closing parts is a panel, which is a ball valve, butterfly valve plate and the ball valve is rotated around its own axis for movement of the ball valve is a spherical sealing surface.The valve (Valve) is a mechanical device that controls the flow, flow, pressure, temperature, etc. of a fluid medium. The valve is the basic component of the piping system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
- Q: A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve
- Four is 1/2=DN15, 21mm data is not accurate, if it is metric thread, provide tooth pitch and thread diameter.
- Q: What's the difference between a medium-sized ball valve and a heavy ball valve?
- It's almost certain that you made an inquiry at the small valve manufacturer in Wenzhou.In fact, the main wall thickness is differentThe so-called heavy, is in accordance with the GB/T12237 Petrochemical ball valve wall thickness to designThe so-called medium-sized, is in accordance with the GB/T12224 steel ball valve wall thickness to design, two wall thickness of some difference, plus a little steal material, sphere do hands and feet, the price can be much lower.There is a light, that is the material does not meet the standards, basically sold to plumbing builders.
- Q: What's the meaning of the ball valve bore 14 "x 12"?
- The inner diameter of the two ends of the ball valve is 14 inches at one end and 12 inches at the other.
