1PCS Stainless Steel 201/304/316 Wire Port Needle Valve J13W-160P Internal Thread Needle Valve High Pressure Instrument Valve DN6-25.(DN10 3-8,201 Material)

SolenoidsWorking principle:The function of any valve is to cut off the fluid. According to the difference of the valve core, it can be divided into stop valve, gate valve, valve, ball valve, butterfly valve, needle valve, etc. Needle valve can withstand more than other types of valves. The pressure and the sealing performance are good, so it is generally used for the sealing of liquid media such as gas lakes with smaller flow and higher pressure. The needle valve is the most suitable for use with the pressure gauge. The general needle valve shape is made of thread. connect.Nominal pressure: PN2.5/PN4/PN6.4/PN16/PN32MpaNominal diameter: DN5~DN25Applicable medium: oil, water, gas and other non-corrosive and corrosive mediaApplicable temperature: -20°C~+440°C/-70°C~-240°C~540°C570°C, etc.Selection principle:1. For the piping system and device of low-temperature medium, a low-temperature needle valve with a valve cover should be used.2. In the pipeline system of the catalytic cracking unit of the oil refining unit, a lifting rod needle valve can be selected.3. For the acid-base and other corrosive equipment and piping systems of chemical systems, it is advisable to use all-stainless steel needle valves made of austenitic stainless steel and PTFE as the and sealing ring.4. Metal-to-metal sealing needle valves can be used on pipeline systems or devices for high-temperature media in metallurgical systems, power systems, petrochemical installations, and urban heating systems.5. When flow adjustment is needed, a worm-driven, pneumatic or electric adjustment needle valve with a V-shaped opening can be used.6. For oil and natural gas transmission main lines, if the pipeline needs to be cleaned and buried in the ground, use a needle valve with a full-diameter fully welded structure; if it is buried on the ground, choose a full-diameter welded connection or flange connection. Ball valve.7. For the transportation pipeline and storage equipment of the refined oil, a needle valve connected by a flange is used.8. For city gas and natural gas pipelines, use needle valves with flange connection and internal thread connection.9. In the oxygen pipeline system in the metallurgical system, a needle valve that has undergone strict degreasing treatment and flanged connection should be selected.Installation Precautions:1. The installation position, height, and direction of inlet and outlet must meet the design requirements. Note that the direction of medium flow should be consistent with the direction of the arrow marked on the valve body, and the connection should be firm and tight.2. The valve must be visually inspected before installation, and the nameplate of the valve should comply with the current national standards. For valves with a working pressure greater than 1.0Mpa and a cut-off function on the main pipe, the strength and tightness performance test should be carried out before installation, and the valve can be used only after it is qualified. During the strength test, the test pressure is 1.5 times the nominal pressure and the duration is not less than 5min. The valve housing and packing should be qualified without leakage. During the tightness test, the test pressure is 1.1 times the nominal pressure; the duration of the test meets the requirements of national regulations.Anti-corrosion method:1. For the anti-corrosion of the valve body, the main pigments are stainless steel and carbon steel. Although the anti-corrosion resources are abundant, it is not easy to choose the right one, because the problem of corrosion is very complicated. The difficulty in selecting valve body materials lies in not only considering corrosion issues, but also factors such as pressure resistance and temperature resistance, whether it is economically reasonable, and whether it is easy to purchase.2. Take lining measures, such as lining aluminum, lining lead, lining engineering plastics, lining natural rubber and various synthetic rubbers. If the media conditions permit, this is an economical method.3. In the case of low pressure and temperature, using non-metal as the valve body material can often be very effective in preventing corrosion.4. The outer surface of the needle valve body is also corroded by the atmosphere, and generally steel materials are protected by painting.==========Type : ValvesModel Number : J13W-160PWorking medium: : Water, oil, some acid-alkaline mediaNominal pressure: : PN160/16MpaAmbient and fluid tempereature: : -28°C-150°CMaterial: : Stainless steel
