1/16in Ferrule to 1/4in NPT Male 3000psi High Pressure Stainless Steel Needle Valve for Laboratory and Semiconductor 日本

The Structural Composition of Ferrule to Male Thread Needle Valve

valve body: usually made of stainless steel material (such as 304, 316, 316L and other common stainless steel materials) to ensure corrosion resistance and strength.

stem: made of stainless steel, used to control the degree of opening and closing of the valve.

valve seat: with the stem to form a sealing structure to ensure the sealing of the valve.

ferrule connection part: - Ferrules: used in the connection part of the pipe to hold tight, play a role in tightening and sealing. - Nut and other fastening parts: to make the ferrule firmly installed between the valve and the pipe.

external thread part: used for connection with external thread interface, common external thread standards are NPT (American Standard Taper Pipe Thread), PT (British Taper Pipe Thread) and so on.

The Working Principle of Ferrule to External Thread Needle Valve

By rotating the valve stem, the distance between the tip of the valve stem (or the sealing part with the valve seat) and the sealing surface of the valve seat changes. When the valve stem to close the direction of movement, the valve stem and the valve seat close to realize the seal closure of the valve, preventing the flow of media; when the valve stem to open the direction of movement, gradually open the media channel, the media can pass through the valve, and through the valve stem to move the distance can be finely adjusted the size of the flow of media.

1. What is the corrosion resistance of this needle valve?

Our stainless steel ferrule to male needle valve is made of high quality stainless steel, 316 stainless steel, which has excellent corrosion resistance and can operate stably in many corrosive environments. However, the specific degree of corrosion resistance will be affected by the type of medium, concentration, temperature and other factors. If you can provide us with more detailed information about the environment in which they are used, we can more accurately assess their suitability for your application.

2. What is the working pressure range of the needle valve?

The operating pressure range of this needle valve is typically between 3000 psi and 6000 psi. however, this may vary by size and model. When you select a product, we will recommend a needle valve with the appropriate pressure rating for your specific needs.

3. What is the sealing performance of needle valves?

Our needle valves have been subjected to rigorous sealing tests and their sealing performance is reliable. The sealing structure between the valve stem and the valve seat is well-designed, which can effectively prevent the leakage of the medium. However, in order to ensure long-term sealing effect, it is recommended that you follow the correct installation and use methods, as well as regular inspection and maintenance.

4. What is the approximate service life of a needle valve?

The service life of needle valves is affected by a variety of factors, such as media characteristics, frequency of use, operating pressure and temperature. Under normal use and maintenance, its service life can generally reach more than.

5. How to install and maintain?

When installing, please make sure the pipeline is clean, the ferrule is installed correctly and fastened in place, and the external threads are connected tightly and sealed properly. For maintenance, it is recommended to regularly check the flexibility of the valve stem, sealing performance and appearance for signs of damage or corrosion. If problems are found, repair or replacement parts should be made promptly.

6. Do you provide warranty service?

We provide 1 year warranty service for our products. During the warranty period, if the product has quality problems, we will be responsible for free repair or replacement.

7. Can we customize special specification needle valve?

Under certain conditions, we can customize the production according to your special needs. However, customized products may require additional time and cost, please communicate further with our sales team for specific customized requirements and details.
