Stainless steel needle valve manufacturer stainless steel needle valve features
Manual shutoff valves and ball valves can be installed anywhere in the pipeline. Needle valve can withstand greater pressure than other types of valves, sealing performance is good, it is generally used for smaller flow, higher pressure gas or liquid medium seal. The next small series for everyone to introduce stainless steel needle valve manufacturers and stainless steel needle valve features.

Stainless steel needle valve features
1, fluid resistance is small. The drag coefficient is the same as the length of the pipe section;
2, simple structure, small size, and light weight;
3, tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, has also been widely used in the vacuum system;
4, easy to operate, opening and closing quickly, from full open to full off as long as the rotation of 90 °, easy to remote control;
5, easy maintenance, ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient;
6, when fully open or fully closed, the sealing surface of the ball body and the valve seat is isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded;
7. The stainless steel ball valve has a wide range of applications, ranging from small to several millimeters in diameter, up to a few meters in size, and can be applied from high vacuum to high pressure.
Selection principle of stainless steel needle valve
1. On the piping system and device of low-temperature medium, a low-temperature needle valve with valve cover should be selected.
2. On the pipeline system of the catalytic cracking unit of the refinery device, a lifting rod type needle valve may be used.
3, chemical system of acid and alkali and other corrosive medium devices and piping systems, should use austenitic stainless steel, PTFE seat ring for the entire stainless steel needle valve.
4. On metallurgy systems, power systems, petrochemical plants, and high-temperature medium pipeline systems or devices in urban heating systems, metal-to-metal sealed needle valves may be used.
5. When flow adjustment is required, a worm-driven, pneumatic or electric adjustment needle valve with a V-shaped opening can be used.
6. For pipelines for oil and gas transportation, which need to clean pipelines, but need to be buried in the ground, choose the full-diameter, all welded structure needle valve; buried in the ground, choose the full-diameter welding connection or flange connection Ball valve.
7. For the pipelines and storage equipment for refined oil products, use flange-connected needle valves.
8. On the pipeline of city gas and natural gas, the needle valve with flange connection and internal thread connection is selected.
9. In the oxygen pipeline system in the metallurgical system, a needle valve with a strict degreasing treatment and a flange connection should be selected.
Editor's summary: The features of stainless steel needle valve manufacturers and stainless steel needle valves are introduced here, and we hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
