Stainless steel needle valve is the instrument to measure an important part of the piping system , the main shut-off valve and ball valve, its function is to be used to turn on or off the pipeline path .
Card sets with easy installation and removal instrument valves , connections are tight , there is conducive to fire , explosion and high voltage capability , good sealing performance, etc., are power plants, oil refineries, chemical plant piping and instrumentation to measure an advanced connection valve. This type valve in the pipe should generally be installed horizontally.
Stainless steel needle valve sealing a good , long life, even after the sealing surface is damaged, only need to replace wearing parts , you can continue to use.
Should be installed so that the flow is consistent with the direction of the arrow on the valve body medium .
1 , needle valves standards , needle valves with easy installation and removal , needle valve connections are tight , the needle valve is conducive to fire , explosion and needle valve high pressure capability . Needle valve sealing performance advantages of a good valve power plant , oil refinery, chemical plant piping and instrumentation to measure connection in an advanced way . Good sealing needle valve , needle valve long service life , even after the needle valve sealing surface is damaged , needle valves only need to replace wearing parts , needle valves can continue to use. Needle valve should be installed so that the flow is consistent with the direction of the arrow on the valve body medium . Needle valve is a valve can be precisely adjusted broader purposes such as flame cutting with the cutting from the flame temperature adjustment knob is needle valves, instrumentation needle valve instrument measuring the piping system is an important part of the main needle valve there are shut-off valves and ball valves , needle valves whose function is to be used to turn on or off the pipeline path .
Stainless steel needle valve base on self-designed structure , is currently the most popular new generation valve.
First, the body 's anti-corrosion, mainly correct selection of materials . Although corrosion data is very rich, but whether the election was appropriate or not an easy thing , because the corrosion problem is very complex. Choose body material difficulties, lies not only consider the corrosion problem , but must consider the ability to withstand temperature , whether economically reasonable , is it easy to buy and other factors .
