China is one of the countries that can meet many conditions as well as products in the world. We can feel through the fact that now our country has to 85% of the sources of goods imported from this country. Because the sources of goods come from China, there are always certain advantages. And ball valve is no exception, so when you buy Chinese ball valve there are the following advantages.

For large sized valves, you can ask the company to order with the factory. The import time to Vietnam is only from 25 to 30 days. Much faster than brands from the EU or G7.

Can say, ball valvesChina has many different product lines. And one of the points to distinguish the type, the material is also one of the indispensable methods.

Leading the product is still Chinese stainless steel ball valve, why do I say that. The reason comes from the fact that stainless steel valves are always imported in large quantities, and the density of user selection is much larger.

In stainless steel ball valve, it is divided into 3 smaller products, which are 201, 304, 316 stainless steel valves. In which 201 stainless steel ball valves will have the cheapest price, the highest has 316 stainless steel valves.

Told you now to ask the question, what valve is suitable for high temperature systems. More specifically, the steam system can be taken as an example.

The answer is that you can use steel ball valves, instead of other ball valves. Because the temperature is too high, if you use a kettle made from plastic or cast iron and stainless steel. This will greatly reduce the valve"s durability.

For steel ball valves, the smallest size is DN32, and only one type of flange connection without thread is used. Flanges are manufactured according to BS standards, if you want to use JIS or ANSI standards, they are not available.

Chinese ball valves are made from copper material, and are quite small in size. Simply from dn15 to dn50. For copper, the main use is still clean water, and some basic steam systems do not exceed 150 degrees Celsius.

Compared to the two valve lines that I have just shared above, the Chinese bronze ball valve is much cheaper. Therefore, chemical systems should not use copper valves. You must switch to using plastic or stainless steel valves.

The final product today is a line of ball valves made from plastic. If stainless steel valves have 3 smaller valve lines from materials, then plastic valves are not inferior at all. Materials used to manufacture plastic ball valves include the following materials: PVC, UPVC, CPVC, PPH.

Not a product that uses all of the above materials, but each type of valve will use a material. The highest is still the valve made from PPH plastic material.

To understand what parts the Chinese ball valve is composed of, you only need to pay attention to the following main parts. And these parts apply to every other line of ball valves, differing only slightly in the material part.

Hand lever: For the lever is an indispensable part for the ball valve, if you need it, you can replace the lever with electric or gas. In this case, these controllers may come from a third party that our company imports, which is not from China.

Ball valve: Butterfly valve gate valve has vane, but for Chinese ball valve, there is a ball valve part. This is also the reason why the name ball valve was born. Machined in a circular shape, so that the friction is minimal. Both ensure a tight seal to the body and the opening process is smooth and gentle.

Valve shaft: The shaft is attached to the device, the top allows the lever to be attached. So when you turn the lever, the valve shaft and the ball below also rotate. Shafts are always made from stainless steel, only steel ball valves are made of steel.

What we need to do to change the opening and closing state for the valve, just apply force to the lever and pull in the right direction. That the manufacturer has proposed, to know how to open and close you can look at the arrow on the lever.

When pulling the lever clockwise and parallel to the flow, the valve will open. If you want to close the valve, you need to pull the lever back to finish.

For Chinese ball valves, in choosing a valve you also need to pay attention to some of the following notes. This helps you to limit unnecessary mistakes, the second one helps you get the most suitable product. In simpler terms, it is to limit the risk when shopping.

The first is to see if the investor has specified any products or not. If specifying certain products, which are not valves from China. Should reconsider buying and choosing.

Early boilers operating without one were vulnerable to accidental explosion.Vacuum safety valves (or combined pressure/vacuum safety valves) are utilized to prevent a tank from collapsing even though it is being emptied, or when cold rinse water can be used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures.

Subsurface Safety Valve TRSSSV is a kind of tubing retrievable safety valve which is controlled at the surface. It directly connects to the tubing string. There is a hydraulic control line connecting to the safety valve from the ground. While a certain amount of pressure is supplied through this control line to the safety valve, the valve remains open; while the pressure is released, the safety valve will close and the tubing pass is closed at the same time.

Pilot operated safety valve, newly-structured, is mainly applied to such trades as petroleum & nat-ural gas, chemistry, electric, meta-llurgy & burning gas. It is the best super-pressure protecting equipment on press equipment, container, or pipeline, It is mainly characterized by shifting direct function of spring to indirect function of guide valve. What"s more, main valve, applying for sleeve piston & double sealed seat, is characterized by high pre-cision of action, good recycling function, fast turning back to seat, ability to high-pressure leaking, long working time & security, toge-ther with read-justment on line,
