Imported butterfly valves for water treatment pipelines, about the butterfly valves in pipelines.

The handsome guy on the first floor PN10 = This can be done with three eccentric metal hard seal butterfly valves, or with PTFE material for sealing elements, but the specific corrosion of ten-inch valves can be done by general manufacturers.

In addition to the caliber scale, you need to provide the manufacturer with the following data: connection form (LUG, RF, WF, RF-SLP), connection standard (national standard or American standard or other), working environment medium, whether it is recommended to use a certain actuator (foreign more expensive but better, domestic cheaper, or recommended by the first business), whether the main material is recommended (if there is no ** chamber of commerce recommendation, this should be made of stainless steel), sealing material (PTFE is generally used for water treatment, no pollution), Are there any other requirements for motorized heads.

If you are lazy, directly provide those you say **Chamber of Commerce will give you options. If you want to find a cheap deal, just one of them.

It is not possible to use a butterfly valve for a system with a pressure of PN10, or a gate valve. Butterfly valves are generally used in systems where the design pressure is lower. If you really want to buy butterfly valves, Xiamen Freit's products are good.

pn10?Does the landlord refer to 10mpa?

Metal hard seal is the structural form of the valve body, which has nothing to do with the electric actuator, and the general valve body and actuator will not be produced by the same manufacturer.

The landlord can consult bray, Chinese name Bolei, the water treatment industry has used more in recent years.

As for such butterfly valves, in the petrochemical industry, they are low-grade valves, and butterfly valves are basically not used.

I also do water treatment engineering.

This one is better, an international brand, specializing in butterfly valves.

This is a turbine-to-clamp butterfly valve, is it difficult to make trouble? The flange is dedicated to butterfly valves, and the screws are made of high strength, and the installation principle is the same as that of the valve.

This is a double-clamp soft-seal butterfly valve, and the two flanges of the two pipes clamp the butterfly valve in the middle.

This is a clamp-on eccentric butterfly valve, welded with the special flange of the butterfly valve at both ends of the pipeline (the nominal pressure level of the flange and the nominal pressure level of the butterfly valve should be the same), and then the bolt is passed through the 4 ear holes of the butterfly valve, fixed on the flange, and fixed with bolts on both sides. If shown.

Answer: The pipeline butterfly valve plays the role of cutting off, stabilizing the pressure and adjusting the flow, and the valve disc is opened according to the requirements of the design pressure and flow, and will not cause damage to the valve stem or disc.

According to different types of flowmeters, there should be a straight pipe section installed in front of the valve, generally 5-8 times the pipe diameter (according to the design or manual), the shut-off valve is a little unstable when it is just opened and adjusted, and after a period of time, the flow value is stable.

The adjustment performance of the butterfly valve is not good, but your caliber is too large, you can only use the butterfly valve to adjust the valve, and the butterfly plate has 10 angles when opening and closing.

The butterfly valve for swimming pool water treatment can be used in a conventional model, and there is no need for a special design.

The butterfly valve is the butterfly valve, and the design drawing can be selected and installed correctly.

Generally, the butterfly valve is used for water pipes, and it is not good to thread more than 3 inches, and the thread ball valve is easy to leak, and it is also very troublesome after disassembly and assembly, while the butterfly valve is cheap, and the water pipe has not so high requirements for internal leakage.

Without this regulation, butterfly valves are cheap, and many companies like to use them in order to save money, but they are easy to leak.

You can use the butterfly valve, the butterfly valve is cheap, but it should be replaced every year, overhauled, if necessary, you can call me ** inquiry.

It mainly depends on your connecting end, and if you are flanged, there is no big problem in aligning the flanges at both ends. If it is welding, both ends are welded. In this way, the middle of the butterfly valve is naturally aligned with the center of the pipe.

Yes, mainly because of its structure, the middle stem is stressed in a complex way, and the pressure is too thick for the stem to have no flow, rather than the reason for the good sealing.

For drops, because of the low pressure, a good seal can be achieved.

Yes, the production of butterfly valves is generally made of cast iron, 10kg, 16kg is very common, and others have basically not been produced.

The wear-resistant butterfly valve is the most suitable, the valve seat is made of wear-resistant rubber X6, the valve body valve plate is on the line, the cast iron body, ductile iron plate can be, Tianjin Kete Valve Factory produces cement special butterfly valves.

Gate valves and butterfly valves can be used.
