Do you know more about Brass ball valve

Ball valves has a muted yellow color, somewhat similar to gold. It is relatively resistant to tarnishing, and is often used as decoration and for coins. In antiquity, polished brass was often used as a mirror.
Brass is the proportions of zinc and copper can be varied to create a range of brass ball valve with varying properties.In comparison, bronze is principally an alloy of copper and tin.
Despite this distinction, some types of brasses are called bronzes. Brass is a substitutional alloy.It is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, ammunition, and valves; for plumbing and electrical applications; and extensively in musical instruments such as horns and bells for its acoustic properties.
Now with that background, which filter is best? I often use this question to gauge who I am talking to in a pool store. Just ask: "Which filter is best" and then listen for the answer. There is only one correct answer to that question: can you please define best? If the answer is any of the three, someone is trying to simply sell you something. Brass was used to make fan blades, fan cages and motor bearings in many antique fans that date before the 1930s. Brass can be used for fixings for use in cryogenic systems, however its use is not limited to this.
We supply different kinds of brass ball valves, size from 1/4" to 4". Brass ball valves working medium: water, gas. The ends of thread F/F. F/M. M/M are the normal ball valves, but we can also supply the ball valves for PEX pipes. Straighter normal brass valves, angle valves and mini ball valves are all available. For the body of ball valve, we can make it from brass and zinc, and for the ball, it is usually made from brass chrome plated, but if you need cheaper, we can make it in steel chrome plated. The brass ball valves thread standard: ISO228/ISO7/1.

Manifold valves

We are main exporter of different kinds of manifold valves and filter valve in China, including brass bar manifolds, manifolds with female/male ways, manifolds for pex pipes, water separators, manifolds with valves sets, the filter valve size have: 16x3/4" F/M 16x1"F/M and so on; brass color, nickel plated and chrome plated are all avaible.
Improper design of a sprinkler system will always result in the worst consequences for your lawn, including overly wet or dry areas. Essential to the design of a sprinkler system is its valve manifolds, which divide the distribution of water into zones. It is important to build valve manifolds properly in order to ensure durability and efficiency. Luckily, building a valve manifold properly is a task that almost anyone can accomplish if given the right instruction.
1、Wrap Teflon tape around the treads of the tube adapter, threaded valve ends, and all of the close nipples. Don't wrap too much Teflon tape around the threads; three times around should be fine.         
2、Insert the tube adapter into one of the elbows by turning it clockwise. Get it as tight as you can with your hand, and then use the channel locks to tighten it two full turns more. Insert a valve into into the other elbow and secure it in the same way you did the tube adapter.         
3、Insert any addition valves into the perpendicular end of a "T" fitting (one valve per fitting), and secure it using the same method as before.         
4、Join the PVC fitting by threading them together with the close nipples using the same method as before. Make sure to start with an elbow, join all the "T" fittings in a line facing the same direction and loosen the valves if necessary to face them all right-side-up. Finish by threading the last elbow onto the final open "T" end with a close nipple.
