Introduction and application of instrument and valve
General instrument valves are made of stainless steel. The common specifications and parameters are: Product Name: Denis imported needle valve type range: screw type / ferrule / welding size range: dn6-dn25 temperature range: - 40 ℃ - 600 ℃ pressure range: * high pressure 10000psi valve body material: A105, 304, 304L, 316, 316L, wc6, wc9 valve seat material: stainless steel + PTFE + ppl + wc6, wc9 scope of application: water, oil, gas, etc.
Instrument valve is a kind of pipeline accessory. It is used to change the channel section and medium flow direction, and control the medium flow. Specifically, instrument valves have the following uses:
(1) Connect or cut off the medium in the pipeline. Such as gate valve, globe valve, ball valve, plug valve, diaphragm valve, butterfly valve, etc.
(2) Adjust and control the flow and pressure of medium in pipeline. Such as throttle valve, control valve, pressure reducing valve, safety valve, etc.
(3) Change the direction of medium flow in the pipeline. Such as distribution valve, three-way cock, three-way or four-way ball valve.
(4) Prevent the medium in the pipeline from flowing back. Such as check valve, bottom valve, etc.
(5) Separation medium. Such as a variety of different structures of steam trap, air trap, etc.
(6) Indicate and adjust the liquid level. Such as liquid level indicator, liquid level regulator, etc.
(7) Other special uses. Such as temperature control valve, over-current protection emergency shut-off valve, etc.
