The needle valve is easy to install and disassemble, the needle valve is tightly connected, the needle valve is conducive to fire prevention, and the needle valve has high explosion-proof and pressure resistance. The needle valve has the advantages of good sealing performance and is an advanced connection valve in power stations, oil refining, chemical equipment and instrument measurement pipelines. The sealing of the needle valve is good, and the service life of the needle valve is long. Even if the sealing surface of the needle valve is damaged, the needle valve only needs to replace the vulnerable parts and the needle valve can continue to be used.
The valve controls the flow of fluid by moving the valve switch rod up and down. There is one or more valve plates on the valve switch rod. When the valve switch rod moves upward, the valve plate will rise at the same time, thus opening the valve path and making the fluid pass through the valve; When the valve switch rod is moved downward, the valve plate will drop at the same time, thus blocking the valve path and preventing fluid from passing through the valve.
Stainless steel needle valve is an important part of the instrument measurement pipeline system, mainly has the globe valve and ball valve, its function is to open or cut off the pipeline path
