Q: What's the diameter of the 4 point ball valve?: 4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.

Q: What q25r-j159 BB-F-TE-NB represents American Standard ball?: American Standard top mounted hard seal fixed ball valve modelQ: valve type - ball valve, BALL, VAVE2: pressure class -150cl pounds scale5: structural form - tethered body, top mounted, fixed ball (abbreviated BB-F-TE-NB)R: connection form -RF convex mesa flange connectionJ1: body material -A216-WCB cast carbon steel59: spool material -13%Cr

Q: The difference between ball valve Q341F and Q347F: Ball valves Q341F and Q347F are straight through flow, worm drive, flange connection, soft sealing form. Different from Q341F, it is a floating ball structure, and Q347F is a fixed ball structure.Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve;

Q: What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?: The structure of valve and butterfly valve, and determines the price of the different use of the environment. The same nominal diameter of the butterfly valve and ball valve has the advantages of simple structure, low cost, adjustable range, liquid and gas valve is usually applied to non particulate impurities like fluid, small pressure loss, good sealing performance, high cost. Generally speaking: small caliber election ball valve, large caliber butterfly valve.

Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?: PN nominal pressure.Definition：Relating to the mechanical and dimensional characteristics of the components of the piping system and the identification of letters and combinations of numbers for reference. It consists of letters PN and followed by dimensionless numbers.Note 1: numbers followed by letters "PN" do not represent measurements and are not used for purposes of calculation unless otherwise specified in the relevant standards.Note 2: is not associated with the relevant pipe component standards, but the term "PN" does not make sense.Note the 3: piping element allows the pressure to depend on the PN value of the element, the material and design, and allows the operating temperature, etc., to allow the pressure to be given in the corresponding standard pressure temperature class table.Note 4: all pipe elements with the same PN and DN values shall have the same mating dimensions as their flanges.The latest definition of PN comes from standard GB/T 1048-2005, the definition and selection of pipe component PN (nominal pressure), and is referenced in the standard of pipe fittings and tubing. GB/T 1048-2005 7268:1996 Pipe components - modified ISO/CD Definition of nominal pressure, a "note increase than the original standard: allow numerical" choose other PN when necessary, namely in the PN series, you can use other numerical PN.

Q: 3/43/8 above the ball valve is not usually said of the big ball valve?: That is the calculation of the imperial, generally divided into two types, 1 inch (in.) 2, metric (mm) swap inch metric 1/4 (2) =6 3/8 (3) =10 1/2 (4) =12 5/8 (5) =16 3/4 (6) =18 7/8 (7) =22 1 1/8 (1 inch 1) =28,

Q: 3/4 on the elbow of the water pipe. How about that ball valve?: 3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material

Q: Is the ball valve switch in front of the water meter or after the water meter?: the owners of their own decoration or repair, in front of the water meter is generally C type locking valve or valve, if less water, property control, no special key you open

Q: What's the difference between a medium-sized ball valve and a heavy ball valve?: Medium and heavy duty difference is several kilograms, heavy material is not false, and temperature resistance, and pressure performance is better, long life!
