Q:What does "S" mean by ball valve Q11S?

S is the body material code, plastic.

Q:O ball as general regulation of opening extent

According to the actual demand, turn 90 degrees from the closed state to the maximum opening.

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:What does "q341" and "q347" mean?

Valve type explanation:Q stands for ball valves;3 represents worm gear drive;4 represents flange connection;1 represents straight through floating ball, and 7 represents straight through fixed ball.Therefore, Q341 is a turbine driven flange straight through floating ball valve, Q347 is a turbine drive flange through fixed ball valve.

Q:What does the RTFE say in the ball valve?

RTFE reinforced PTFE is more wearable than PTFETeflon PTFEThe seat of tetrafluoroethylene specified for a temperature range of ~200 DEG C -32. High temperature resistance and chemical resistance. Because of its high density and good permeability, PTFE can also prevent the corrosion of most chemical media.Conductive PTFE is an improved PTFE product that allows the current to pass through the lining and thereby cancel the insulation properties of ptfe. Because of its conductivity, conductive PTFE can not be checked by edm.+ reinforced PTFE RTFERTFE is a modification of PTFE material. Pure PTFE although very low coefficient of friction (0.02~0.04) but the wear volume is great, but also because of its easy creep, poor mechanical properties, low bearing capacity, poor dimensional stability characteristics such as friction material has great localization. Only modified by compound method to meet the special requirements of all walks of life sealing material on the wear resistance, to improve the wear resistance of PTFE, can be incorporated into some wear-resistant materials such as glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder and some organic compounds, making them reticular junction formed in the PTFE layered structure so as to improve the the stiffness, thermal conductivity, creep resistance, and greatly improve the wear resistance.PTFE is composed of tetrafluoroethylene monomer polymerization of the polymer, the wax is similar to a PE transparent or opaque, its density is 2.2g/cm3, the water absorption rate of less than 0.01%. Its chemical structure is similar to that of PE, except that all hydrogen atoms in polyethylene are replaced by fluorine atoms. Because the C-F bond is high and stable in performance, it has excellent chemical resistance

Q:How to distinguish three points copper ball valve, two points copper ball valve

Three points, two points mean the specifications of the ball valve, three refers to the diameter of 32, two refers to the diameter of 25

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:Home PPR pipe ball valve, which is good?

Brother, brother to do plumbing business for more than 10 years, to be conscience, you'd better use the cut-off valve, ball valve in the South with the north, with cut-off valve, I was in Jiangsu, Taizhou, Jiangsu here have Taizhou as the boundary, the cut-off valve generally more in Taizhou Xinghua City, Taizhou Jiangyan Taixing Jingjiang more have ball, but the ball after the bad ball will change to buy the same brand, but also the same type, so that we can have, to buy is to cut off the new hot. Some hydropower workers have done you a dead distance, you can not re - hot, only in the water and electricity market crazy looking. But if the ball valve has the same brand, bad, they can exchange, very simple. The stop valve is broken. You should find a plumber to pay for it. But, the valve is not easy to bad, and indeed, the bad, you have to find the master for the spool, there must be professional tools, the spool is the same, so do not worry, not yet. Ball valve is also good, not easy to bad, but partial expensive, we use the ball valve Cowell tube industry, quite good. Total copper. There's one in Jiangyan that's on sale. The quality is absolutely OK

Q:What is the nominal pressure 1.6p of a ball valve?

Nominal pressure: reference value relating to the pressure resistance of a piping system. For ease of use, usually the priority of the R10 series is taken. Nominal pressure refers to the pipe in the two temperature (20 degrees Celsius) when the water delivery pressure. If the water temperature is between 25 and -45 degrees, the coefficient of temperature drop should be adjusted to correct the working pressure.

Q:Replacement method of PPR hot melt ball valve

1, need to replace the valve, if the valve is flange or wire connection type, directly open flange or loosen the screw, the ball valve can replace a broken;
