Product Description:

Metal-to-Metal Seal Ball Valves

Metal-to-Metal Seal Ball Valves are usually used in the industrial controlling pipeline services of high pressure, high temperature, severe corrosion and solid material containing industry, such as coal chemical, polysilicon and vitriol/ nitric acid. The leakage rate of metal-to-metal seal control ball valves can reach rate V. Top flange is designed per ISO5211 for easy amount various type of actuator.

Q:What is the service valve?
In front of the valve will need to be all pass, that is, the hole and the ball valve line diameter consistent, the ball will not be card.
Q:Family aluminum tube ball valve, with a long handle so that, or butterfly shaped handle so that?
Butterfly type unused, a long handle used, the quality is very good.
Q:The hot water pipe ball valve what brand alone?
The rn angle valves are generally new home decoration essential water heating accessories, and play the role of a beautiful.
Q:How can a steel ball in a steel ball valve be put in?
This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.
Q:What does copper ball valve type Q11F-16T mean?
Q refers to the ball valve, 1 refers to the connection mode, the latter 1 refers to the straight through type, F refers to the sealing material, 16 refers to the nominal pressure of 10 times, T refers to the main material for copper material.
Q:Ball valve faucet handle rotation, the ball does not move, how to repair?
That's the valve stem. It didn't eat in the slot. The product was useless. Buy a new one
Q:Into the tap valve, with globe valve or ball valve?
Water valve at home as far as possible not to use the form of valve, gate valve for water, slag better, shut down with the next valve and ball valve. Just don't buy cheap goods, cheap ball valves use a period of time, gland leakage, spool corrosion must be replaced.
Q:Is the two piece ball valve in the direction of the pressure pipe?
Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
Q:Ball valve specifications 1/2 inches corresponding to DN?
[1] 1/2 is DN15, 3/4 is DN20, and 1 is DN25.[2] ball valve: ball valve (ball valve in the field of marine engineering and ships should be cut-off valve), refers to the ball with a circular hole for opening and closing parts, the ball with the stem rotation, in order to achieve Kai [1] closed action of the valve. Standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the square ball valve for the axis of the rotation of the valve.". Use can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.
Q:Why is there a water or oil in the new ball valve?
The test has leaked;Pressure test, lubrication ah!
