Low pressure needle valve

Low pressure needle valve

Use and introduction of low pressure needle valve: The low pressure needle valve is a precisely adjustable valve that is more versatile than other valves. For example, the cutting distance for flame cutting, the knob for adjusting the flame temperature is the needle valve. The instrument needle valve is an important part of the instrument measuring pipeline system. It mainly has a shut-off valve and a ball valve. Its function is to open or cut the pipeline passage. . The purpose of any valve is to cut off the fluid. According to the different spools, it can be divided into globe valves, gate valves, plug valves, ball valves, butterfly valves, needle valves and so on. The spool of the needle valve is a sharp cone that fits into the seat like a needle.

Use and description of low pressure needle valve:
Low pressure needle valve is a kind of precision adjustment Valves are more widely used than other valves. For example, the cutting distance for flame cutting, the knob for adjusting the flame temperature is the needle valve. The instrument needle valve is an important part of the instrument measuring pipeline system. It mainly has a shut-off valve and a ball valve. Its function is to open or cut the pipeline passage. . The purpose of any valve is to cut off the fluid. According to the different spools, it can be divided into globe valves, gate valves, plug valves, ball valves, butterfly valves, needle valves and so on. The spool of the needle valve is a sharp cone, which is inserted into the valve seat like a needle, which is called a needle valve as its name suggests. The needle valve shape is more resistant to pressure than other types of valves and has good sealing performance, so it is generally used for sealing of small flow, high pressure gas or liquid medium. Main parameters: ☆ Nominal pressure: PN2.5 PN4 PN6.4 PN16 PN32Mpa<> Nominal diameter: DN5 to DN25<>Applicable medium: oil, water, gas, etc. A variety of non-corrosive or corrosive media ☆Applicable temperature: -20 ° C ~ +440 ° C -70 ° C ~ -240 ° C ≤ 540 ° C ≤ 570 ° C, etc. ☆ Manufacturing materials: 20 #, 1Cr18Ni9Ti 304, 316, 316L, 12Cr1Mov, etc. Under normal circumstances, the needle valve material should be selected according to the parameters and the properties of the material according to this standard, and should comply with the relevant product standards. Other materials with performance not lower than those specified in this standard or agreed upon by the parties to the purchase may also be used.
