Stainless steel needle valve is an important part of ball valve

Stainless steel needle valves instrument measuring pipeline system is an important part of the main shut-off valve and ball valve, its function is to make open or cut off the pipeline pathway used.
Card sets of Instrument valves have easy installation and removal, connections are tight, there is conducive to fire, explosion and high voltage capability, good sealing performance, etc., are power plants, oil refineries, chemical plant and instrument measuring line in an advanced connection valve. This type valve in the pipe should generally be installed horizontally.
Stainless steel needle valve sealing good, long life, even if the sealing surface is damaged, only need to replace wearing parts, you can continue to use.
Base FD-LOK Stainless steel needle valves structure on self-designed, is currently the most common next-generation valve.
First, the body of anti-corrosion, mainly the correct selection of materials. Although the anti-corrosion materials is very rich, but whether the election was appropriate or not an easy thing, because corrosion problems are complex. Select body material difficulties, it lies not only consider the corrosion problem, but you must consider the pressure temperature capabilities, whether economically justified, is it easy to buy and other factors.
