Needle valve is an important part of the meter in the piping system, mainly cut-off valve and ball valve, its function is used as open or cut off the pipeline pathways. Instrumentation valves of cutting sleeve type has the characteristics of easy installation and disassembly, fastening connections, is conducive to fire, explosion and high crushing ability, sealed performance is good wait for an advantage, is the power station, oil refining, chemical industry and instrument measuring line of an advanced connection mode of the valve. Needle valve sealing good, long service life, even if the sealing surface damage, also need to replace quick-wear part only, can continue to use. When installation should make the flow of medium and the direction of arrow on valve body. Manual stop valve, ball valve can be installed in any position on line.

Action: open or cut off the fluid medium in the pipeline

Applicable medium: water, oil, steam, liquefied petroleum gas (LPG), etc.

Application: type needle valve is a valve can be precisely adjusted, has a wide use, such as flame cutting with the cutting distance, the flame temperature adjustment knob is the needle valve. Instrument type needle valve is an important part of the meter in the piping system.

Advantages: type needle valve type than any other type of valve that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Type needle valve and pressure gauge is used the most appropriate. General type needle valve type screw thread connection.
