Q:What does copper ball valve mean by "1/2"?

1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.

Q:That is to say, there is still a difference The man in the workshop said it was one thing... It's completely confusedHere are the data for the two valves. Please consult with the experts.Ball plug valve, high temperature cast steel, A216Gr.WCB flange, two pass, full quantity type 3, X 150LB RF ball / rod, 13%Cr seat, PTFE handle openBall valve Q41F-150LB-3"

Ball valve refers to the valve for the sphere of the valve, the English BALL VALVE, ball plug valve should be said that the plug valve, the disc is like a plug like, PLUG VALVE in english,

Q:Ask you engineer, 150mm diameter ball valve or butterfly valve, installed in the water supply pipe, water pressure 0.4Mpa, driven by the electric actuator, should much force distance?Sincere thanks, enthusiastic support of net friend.

Reference: ball valve 1000N on the line, butterfly 250N canThis valve with the switch torque is related, each manufacturer according to the workmanship, process switching torque is not the same.You can refer to the recommended value of the actuator manufacturer

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:The working principle of the track type ball valve

Baidu under the Wuxi East valve, have their contact information, you can consult them

Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?

Since the flow direction of the medium through the valve has changed, so the minimum flow resistance of the cut-off valve is higher than most other types of valvesThe ball valve has the lowest flow resistance

Q:For example, how many sizes and pressures are used in the two piece?

First of all, the difference between a ball valve and two chip, three chip ball valve is a ball valve flow, the internal structure of the necking design belongs to the design, the same diameter ball valve products must be smaller than the other two kinds of ball valves flow more. 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:What is the ball valve Q11F -16 material?

If sealed, F stands for fluoroplastic. Valve material is not marked in the model!Q stands for ball valvesThe first 1: threaded connection,Second 1: is the ball valve is floating through the ball,F stands for PTFE- PTFE seals16 represents the nominal pressure of the ball valve is 1.6MPa=16 kg

Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?

1, the valve body and the valve cover as a whole bear cavity, must meet the design manual on the minimum wall thickness requirements, at the same time to add corrosion allowance, at the same time calculation, large value as the wall thickness of 2, then according to the height of gate valve diameter, to ensure that the valve in the fully open under the condition, ensure the seal and the valve cover seal gate, so that we can determine the height of

Q:Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball

There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.
