Product Description:

1.Technical Date:

Size: DN40-DN4000

Nominal Pressure: PN10/PN16/PN25

Operation Temperature: ≤80°C

Suitable Medium: Water.

2.Feature

Its working principle is installed on the pipeline, tighten the nut, the elastic sealing ring under the nut, the role of the gland. Depend on each other's Angle, compression in the outer pipe seal and connection. Had double nut to lock in the largest scale, once more than its largest scale, will rise to limit, effectively ensure the safety of pipeline operation.

Is mainly used for conveying water, oil, gas and particle powder medium pipeline connection, especially suitable for the vibration or have a certain Angle and in bend pipe connection.

Q:What's the name of the valve?
This is the discharge valve, the lower part of the handle protruding part of the valve is the sealing device. The overall material should be brass, which is typically made by equipment manufacturers.
Q:What's the meaning of the "single valve"?
So called" screwed joint"Valve single order, refers to the valve with a live joint, is a more convenient valve assembly and disassembly.
Q:What is a hot melt valve?
The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.
Q:Is there any difference between the valve and the water valve?
There is no difference between the low pressure lubricating oil pump, as long as the excuse right on the line, not to pressure, design pressure ball valve common does not exceed 3MP, the maximum pressure of only small gear pump vane pump is 2.5MP, the other piston pump, gear pump, the pressure is above 6.3MP. Certainly not. Unless using high pressure water pipe valve.
Q:What does the whole copper valve mean?
The whole valve is made of copper material. In addition to the ceramic core.
Q:Valve pressure grade division
Valves are classified by pressure:Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
Q:What do the D373W and D373H of the valve mean?
Upstairs said yes, I have factory production, this butterfly valve.
Q:What does 3/4''mean in the name of the valve?
Valve diameter, that is, we often say 6 points valve, used in English units, with metric units should be DN20.2 points DN84 points DN156 points DN20 (3/4'')1 inches DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN1005 'DN1256 'DN1508 'DN20010 'DN25012 'DN300Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.Because the units have metric (mm) and British (inch) distinction, there are the following methods of address.1., based on the metric system (mm), called DN (metric unit)2., on the basis of the British system (inch), called NB (inch unit)DN (nominal, diameter)NB (nominal, bore)OD (outside, diameter)
Q:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:Who knows what the DE stands for in the valve DE50?
Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
