Q: What's the difference between angle valve and ball valve?: Angle valve is called "angle valve", because its inlet and outlet are 90 degrees angle perpendicular to each other, rather than straight into the ball valve straight out. Angle valve to cut off media, to facilitate the maintenance of terminal equipment, generally used for washbasin, kitchen sink, toilet water tank, water heater, cold and hot water inlet pipe. When an accident occurs in the water pipe or breaks and leaks after many years, then the angle valve is closed, which does not affect the normal water consumption at home and avoids economic losses.The ball valve has the same rotation 90 degrees of movement, different is the cock body is the sphere, has the circular through hole or the passage through its axis. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, shut-off valve, but the recent development of the ball valve has been designed so that it has throttling and control flow, such as V ball valve.

Q: DN15 stainless steel ball valve 304 can withstand much pressure?: First of all, "DN15 stainless steel ball valve 304" is not sure how much pressure it can bear.DN15 refers to the nominal diameter, and 304 refers to the material.

Q: What do you mean by ball valves dn20pn1.6rf?: DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve

Q: What are the uses and characteristics of copper ball valves?: Role of copper ball valve:Brass ball valve in the pipe fluid is mainly used for cutting, distribution and change the direction of media flow, designed as V shaped opening of the ball valve, also has a good flow adjustment function.

Q: Q4110 what is the ball valve? What does each number stand for?: It's Q41-10Q- stands for ball valves; 4- stands for connecting flanges; 1- is straight through floating ball; 10 means valve bore 10If it's Q4110, you're not sure

Q: How many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Big 50, pleaseHow many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Beg you greatly! Don't forget the detailed form!: No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.

Q: What is the principle of forced sealing ball valve? How to achieve mandatory sealing function? Is it suitable for high pressure conditions?: Structural characteristicsForced sealing ball valve combines the advantages of ball valve, gate valve and plug valve. It has the characteristics of good tightness, no wear and tear, erosion resistance, and on-line maintenance.(1) the bevel of the lower end of the forced seal lift stem provides a mechanical wedge tightening force to ensure continuous tight seal.(2) switch no wear, valve switching process, the ball deviates from the valve seat and then rotating, eliminating the friction of the valve seat, to solve the ordinary ball valve, gate valve and plug valve seat wear.(3) the anti erosion lifting stem realizes the rotation of the ball from the valve seat, and the ball and the valve seat perform the switching action without contact. When the valve is open and about to be closed, the fluid flows immediately along the sealing surface in the range of 360 degrees. When the fluid begins to flow, it can flush the impurities on the valve seat. To avoid the high speed fluid in common ball valve opening and closing the micro moments of local scour on the seat, even the harsh conditions of high pressure, can still ensure long-term zero leakage and tight sealing, improve the service life of the forced sealing ball valve.(4) no case single seat design avoids the valve cavity pressure increases and easy to jam problem.(5) good sealing performance, the ball and valve seat sealing surface after special hardening treatment, can not damage the integrity of the seal to meet the very harsh conditions of sealing requirements.(6) easy maintenance valve adopts top mounted structure. After decompression, it can be checked and maintained online, and the maintenance is simplified.

Q: What is the difference between ball valve and butterfly valve?: The butterfly valve consists of valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; and the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the sealing performance of the ball valve than the butterfly valve; butterfly valve structure is relatively simple, generally with low pressure valve, high pressure valve can reach 64 kg. The ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.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 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; the valve can also be divided into soft seal and seal, soft seal valve maximum temperature is below 280 degrees, the pressure is on 64 kg, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms. Shanghai Sino US valve for your answer, for reference.

Q: Three electric ball valve type T and type L what is the difference?: Ball valve: including straight through, three, etc.. Three way ball valve: including L type, T type. Therefore, the three way ball valve is a kind of ball valve! But the regular ball valve means straight through.

Q: For example, how many sizes and pressures are used in the two piece?: A piece of ball valve, the current market pressure of most products below 6.4MPA, two piece ball valve about 12.8MPA products are also common, there are 20MPA, three pieces of ball valves are mostly below 6.4MPA. Know the characteristics and shortcomings of these three kinds of ball valves, you can completely choose according to your own needs.
