Pressure Gage Needle Valve
The effect of any valve for cutting fluid. Depending on the valve core, can be divided into cut-off valve, gate valve,cock, ball valve,Butterfly valveType, needle valve, etc.
Needle valve type
Needle valve type that can tolerate more than other types of valvepressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Needle valve type andPressure gaugeIs used the most appropriate. General type needle valve type screw thread connection.Nominal pressure: PN2.5 PN4 PN6.4 PN16 PN32Mpa: nominal diameter DN5 ~ DN25 applicable medium: oil, water, gas, etccorrosionSex or corrosive medium applicable temperature: - 20 ºC ~ + 440 ºC -- 70 ºC ~ 70 ºC 540 ºC 570 ºC or less or less manufacturing materials such as: 20 #, 1 cr18ni9ti, 304, 304, 316 l, 12 cr1mov, etc
