SS316 Stainless Steel Double Ferrule One-Piece Bonnet Needle Valves
The Ss316 Stainless Steel Double Ferrule One-Piece Bonnet Needle Valves get its name from the extremely pointed cone-shaped valve core that is fitted into the valve seat like a needle. Needle valves are typically used for sealing gas or liquid media with lesser flow rates and higher pressures because they have better sealing performance and can sustain greater pressure than other types of valves. The best application for needle valves is with pressure gauges. Needles valves are typically formed into flanges, threaded connections, and other types of connections.
Ss316 Stainless Steel Double Ferrule One-Piece Bonnet Needle Valves
The valve core of Ss316 Stainless Steel Double Ferrule One-Piece Bonnet Needle Valves is a very pointed cone, which is inserted into the valve seat like a needle, hence the name. Needle valves can withstand greater pressure than other types of valves and have better sealing performance, so they are generally used for sealing of gas or liquid media with smaller flow rates and higher pressures. Needle valves are most suitable for use with pressure gauges. Generally, needle valves are made into threaded connections, flanges and other forms of connections.
The working principle of Ss316 Stainless Steel Double Ferrule One-Piece Bonnet Needle Valves
The function of any valve is to cut off the fluid. According to the difference of the valve core, it can be divided into globe valve, gate valve, plug valve, ball valve, butterfly valve, needle valve and so on.
The needle valve shape can withstand higher pressure than other types of valves, and the sealing performance is good, so it is generally used for the sealing of gas or liquid medium with small flow rate and high pressure. The needle valve shape is used in conjunction with the pressure gauge. The most suitable. The general needle valve shape is made of threaded connection.
The anti-corrosion method of Ss316 Stainless Steel Double Ferrule One-Piece Bonnet Needle Valves
First of all, the anti-corrosion of the valve body is mainly made of stainless steel and carbon steel. Although there is a wealth of anti-corrosion information, it is not easy to choose the right one, because the problem of corrosion is very complicated. The difficulty in choosing the valve body material lies in that we should not only consider the corrosion problem, but must also consider factors such as pressure and temperature resistance, whether it is economically reasonable, and whether it is easy to purchase.
The second is to take lining measures, such as lining lead, lining aluminum, lining engineering plastics, lining natural rubber and various synthetic rubbers, etc. If the medium conditions permit, this is a saving method.
Thirdly, when the pressure and temperature are not high, using non-metal as the main material of the valve can often prevent corrosion very effectively.
In addition, the outer surface of the needle valve valve is also subject to atmospheric corrosion, and general steel materials are protected by painting.
