Function of needle valve SHV4

 
1. Precise flow control: The main function of a needle valve is to control the flow of the medium by adjusting the rise and fall of the valve core. Its unique needle shaped valve core design reduces the contact area between the valve core and the valve seat, thus enabling more precise flow regulation.

 
2. Simple structure and easy operation: Needle valves are composed of components such as valve body, valve cover, valve stem, valve core, and valve seat, with a simple structure and easy operation and maintenance. By rotating the valve stem to raise or lower the valve core, the gap between the valve core and the valve seat can be changed, thereby controlling the flow rate of the medium.

3. Wide applicability: Needle valves are suitable for various media, including gases, liquids, and corrosive media, making them widely used in laboratory, chemical, pharmaceutical, and other fields.

Characteristics of needle valve SHV4

1. High regulation accuracy: Due to the small contact area between the valve core and valve seat, needle valves can achieve more precise flow regulation, which is crucial for industrial processes that require fine control.

2. Small flow loss: The valve core design of the needle valve reduces the resistance of the medium passing through the valve, reduces flow loss, and improves the energy efficiency of the system.

3. High reliability: Needle valves have a simple structure and no leakage points, therefore they have high reliability. This is crucial for ensuring the continuity and safety of industrial processes.

4. Wide applicability: Needle valves are not only suitable for general media, but also for corrosive media, making them effective in various industrial environments.

5. High pressure loss: Due to the small gap between the valve core and valve seat, there will be a significant pressure loss when the medium passes through the valve. This should be taken into consideration when designing the system. 

6. Suitable for high temperature and high pressure environments: The specially customized needle valve structure can be used in high temperature and high pressure environments.
