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 used is pipe fittings manufacturer appropriate. The general type needle valve type screw thread connection. Nominal pressure: PN2.5 PN4PN6. 4 pn16pn32mpa: nominal diameter DN5 ~ DN25 applicable medium: oil, water, gas and other non corrosive or corrosive medium applicable temperature: - 20 ℃ ~ + 440 ℃ -- 70 ℃ ~ 240 ℃ 540 ℃ 570 ℃ or less or less manufacturing materials such as: 20 #, 1 cr18ni9ti, 304, 316, 316 l, 12 cr1mov, etc.
The characteristics of type needle valve and what is it used for? Device type needle valve should make the flow of medium together with the direction arrow on the valve body. Manual stop valve, ball valve can be in any position of the pipe line; Needle type globe valve is a valve can accurately adjust use widely, such as flame cutting with the cutting distance, the flame temperature adjustment knob is the needle valve, whose hands type valve is outside appearance measurement is an important part in the piping system, mainly cut-off valve, j23w male cut-off valve and ball valve, its purpose is for open or block the pipeline pathways. Needle type globe valve valve core is a very sharp cone, like the needle into the same seat, hence the name. Type needle valve type than other types of j23w external thread globe valve can tolerate more tube fitting manufacturer pressure, good sealing function, so commonly used for small flow, high pressure gas liquid medium may seal; Convenient device apart and fastening cohesion, to fire, explosion and compression ability, outstanding sealing function; Outstanding sealing, long using life, even after the sealing surface damage, also only needs to replace quick-wear part, can continue to use; Needle valve and pressure gauge cooperation using Z is appropriate.
Needle valve type function type valve is an important part of the meter in the piping system, mainly cut-off valve and ball valve, needle valve type is used for open or cut off the pipeline path. Needle valve has the advantages of good sealing, long service life. Even after the sealing surface damage, only need to replace quick-wear part, may continue to use. When installing type needle valve 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. Needle valve can 14 tube fitting be accurately adjusted valve USES broad, such as flame cutting with the cutting distance, the flame temperature adjustment knob is the needle valve. Needle valve valve core is a very sharp cone, like a needle inserted into the seat.
Ball valve ball valve opening and closing by stem drive, round ball valve axis rotation movement of the valve, can be used to adjust and control of the fluid. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, suitable for switch, cut off valve use.
