Needle valve spool is a very sharp cone, like a needle inserted into the seat as the eponymous. Needle valve than other types of valves that can withstand greater pressure, good sealing performance, it is generally used to seal small flow, high pressure gas or liquid medium. Needle valve and pressure gauge with the use of the most appropriate, and generally are made of needle-shaped valve threaded connections, flanges and other forms of connection.
In the pipeline system is an important component of the valve, the main shut-off valve and ball valve, its function is to make open or cut off the pipeline pathway used. Card sets of instrumentation 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.
Widely used: oil refining, chemical, oil, gas, food, pharmaceutical, and other instruments.
