648C Manual Stainless Two Way Needle Valve 6.35mm High Pressure

High Pressure Flow Control Female Thread SS Needle Valve

1. SS needle valve is an important part of instrument measurement pipeline system, which mainly includes globe valve and ball valve. SS needle valve’s function is to open or cut off the pipeline.

2. The ferrule type instrument valve has the advantages of easy installation and disassembly, tight connection, good fireproof, explosion-proof, high pressure resistance and good sealing performance.

3. SS needle valve is an advanced connection type valve in power station, oil refining, chemical plant and instrument measuring pipeline. This kind of valve should be installed horizontally in the pipeline. The SS needle valve has good sealing performance and long service life.

4. Even if the sealing surface is damaged, SS needle valve only needs to replace the vulnerable parts and can continue to use.During installation, the flow direction of medium shall be consistent with the arrow direction on the SS needle valve body.

Anti corrosion method
First of all, the anti-corrosion of the SS needle valve body is mainly the correct selection of materials. Although the data of anti-corrosion is very rich, SS needle valve is not easy to choose the right one, because the problem of corrosion is very complicated. The difficulty in selecting SS needle valve body materials lies in not only the corrosion problem, but also the pressure and temperature resistance, economic rationality and easy purchase.
The second is to adopt lining measures, such as lead lining, aluminum lining, engineering plastics lining, natural rubber lining and various synthetic rubber lining.
Thirdly, in the case of low pressure and temperature, using non-metal as the main material of valve can often effectively prevent corrosion.
In addition, the external surface of SS needle valve is also corroded by the atmosphere.
