Specifications of Stainless Ball Valve

2.certificate:ISO 9001/CE

3.ideal for pipeline

Q: What do you mean by 266 in the 266 brass ball valve?: In order to consider the cost, some manufacturers put in different environment in accordance with the actual need in addition to the basic properties (such as gas safety requirements, key strength, air conditioning temperature, focus on material and penetration, ordinary water can have the basic properties, can economic production and product classification), but in the national standard of the same specifications or inside them the same type,

Q: Manual ball valve type: Class400, 20 ', what does that mean, industrial knowledge?: The pressure rating of the valve type and American StandardIt's a 20 inch, 400 pound valve20 inch =DN500 (nominal diameter)400 pounds equivalent to nominal pressure PN64 Mpa

Q: The difference between ball valve Q341F and Q347F: 7: fixed ball valve, F: fluorine plastic valve seat sealStructural distinction:Floating ball: ball valve is floating, in the media under pressure, that the ball can produce a certain displacement, and tight at the outlet end of the sealing ring, to ensure that the export side seal, a single side forced seal.Fixed ball: the ball of the ball valve is fixed, the pressure does not produce movement, therefore, in the design, two sealing ring should be sufficient pre tightening force to ensure sealing, double sided forced seal.

Q: Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?: Full diameter ball valve flow resistance is minimal, the flow resistance of the globe valve is large

Q: For the master enlighten Q47 ball seat spring hole number is determined by how: Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameter

Q: What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?: (3) butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric three, the eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg;(4) the valve can also be divided into soft seal and seal, soft seal valve can reach the highest temperature below 280 degrees, the pressure is below 64 kilograms, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms.

Q: Stainless steel ball valve Q41F-16P DN80 weight is: The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers

Q: I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......: 2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.

Q: Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!: I don't know. Solid geometry will happen. God knows me. Suddenly, barriers and French goods

Q: I've seen a lot of hot water projects. Why do most of them use globe valves, and ball valves are seldom used?.Globe valves have those benefits compared to ball valves (because the cut-off valve is more expensive, I think it is more expensive and more useful. It must have some advantages in that respect.)Is the stop valve more durable than the ball valve?What are the specific differences between the two PPR valves?: The PPR valve is plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.Ball valve has compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide methane and ethylene, etc., are widely used in various industries. Ball valve body can be integrated, or can be combination.

Our company is specialized in the production of a series of products, such as knife style gate valves, various types of metal hard sealed ball valves, PTFE soft sealed ball valves, high temperature and pressure wrought steel ball valves, eccentric semi-spherical valves and three way valves (T-pattern, Y-pattern and L-pattern), which are designed and manufactured according to international standards, like GB, ANSI/API, JIS and DIN. The main body materials of valves are LCB and LF.
