Features Stainless Steel Needle Valve High Temperature High Pressure Needle Valve
The needle valve is easy to install and disassemble, the needle
valve connection is tight, 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, etc. It is an advanced connection valve in the
power station, oil refining, chemical plant and instrument
measurement pipeline. The needle valve has good sealing
performance, and the needle valve has a long service life. 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. When installing the needle valve,
the flow direction of the medium should be consistent with the
direction of the arrow on the valve body. Needle valve is a kind of
valve that can be precisely adjusted. It is widely used. For
example, the knob used for flame cutting to adjust the flame
temperature is the needle valve. The instrument needle valve is an
important part of the instrument measurement pipeline system. The
needle valve is mainly There are globe valves and ball valves, and
the function of needle valves is to open or cut off pipeline
passages.
Self-designed on the basis of the structure of stainless steel
needle valve, it is a new generation valve that is widely used.
First of all, the anti-corrosion of the valve body is mainly the
correct selection of materials. Although the anti-corrosion
information is very rich, it is not easy to choose the right one,
because the problem of corrosion is very complicated. The
difficulty in selecting valve body materials is that not only the
corrosion problem, but also the pressure and temperature resistance
capability, whether it is economically reasonable, and whether it
is easy to purchase must be considered.
