Male to Female Stainless Steel 304 Adjustable Needle Valves
Male to Female Stainless Steel 304 Adjustable Needle Valves are typically used for sealing gas or liquid media with little flow and high pressure (such as steam, oil). These valves have good sealing performance. The internal thread needle globe valve has a long service life and good sealing performance. Only by replacing the wearing elements can it be used even if the sealing surface is broken. It serves as a connecting valve in power plants, oil refineries, chemical plants, and pipelines used for instrument measurement.

Male To Female Stainless Steel 304 Adjustable Needle Valves have good sealing performance and are generally used for the sealing of gas or liquid (such as steam, oil) media with small flow and high pressure. The internal thread needle globe valve has good sealing performance and long service life. Even if the sealing surface is damaged, it can continue to be used only by replacing the wearing parts. It is a connection valve in power station, oil refining, chemical plant and instrument measuring pipeline.
The anti-corrosion principles of Male To Female Stainless Steel 304 Adjustable Needle Valves
The anti-corrosion of the valve body is mainly the correct selection of materials. The choice of valve body material is difficult, and not only the corrosion problem must be considered, but also the ability to withstand pressure and temperature, whether it is economically reasonable, and whether it is easy to purchase and other factors.
The second is to take lining measures, such as lining lead, lining aluminum, lining engineering plastics, lining natural rubber and various synthetic rubber. It's a way to save money if you can.
Thirdly, when the pressure and temperature are not high, the use of non-metallic valve body materials can often be very effective in preventing corrosion. In addition, the surface of the needle valve body is also corroded by the atmosphere, and the general steel material must be brushed to protect it.
The installation of Male To Female Stainless Steel 304 Adjustable Needle Valves
1. The installation location, height, inlet and outlet directions must meet the design requirements. Note that the flow direction of the medium should be consistent with the direction of the arrow marked on the valve body, and the connection should be firm and tight.
2. The appearance of the valve must be inspected before installation. For valves whose working pressure is greater than 1.0mpa and whose function is to cut off the main pipeline, strength and strict performance tests should be carried out before installation, and qualified valves should be used. During the strength test, the test pressure should be 1.5 times the nominal pressure, the duration should not be less than 5 minutes, and the valve shell and packing should be qualified without leakage.
