J23W-2205 double-phase steel needle valve,double-phase steel needle valve,needle valve

The overall material is made of 2205 duplex steel, which is resistant to acid corrosion. It features manual switch, straight-through structure, needle or conical valve core, external thread connection + matching welded pipe. The valve seat seal is the main body. The valve seat seal of J23F is made of polytetrafluoroethylene, and that of J23Y is made of surfacing STL combined for wear resistance. Nominal pressure: Nominal diameter: DN5 to DN25 \ nApplicable media: oil, water, gas and other non-corrosive or corrosive media \ nApplicable temperature: -20℃ to +440℃, -70℃ to -240℃, ≤540℃, ≤570℃, etc. \ nManufacturing material: 2205

Ii. Material Characteristics of J23W-2205 Duplex Steel Needle Valve

These are precipitation-hardening stainless steels, which contain 35% to 40% austenite in a ferritic matrix. Their yield strength is approximately twice that of 19Cr-9Ni austenitic stainless steel, and they possess high hardness as well as good plasticity and impact toughness. It is particularly suitable for use in corrosive working conditions that involve both abrasion and erosion, and thus is widely applied in strong acid working conditions that involve both oxidation and reduction. It also has special resistance to stress corrosion cracking in environments with chlorine. The operating temperatures of CD-4MCu, CD3MN, CE3MN and F53 duplex stainless steels range from -29 to 316℃.

Iii. Characteristics of J23W-2205 Double-phase Steel Needle Valve

It can withstand greater pressure than other types of valves and has good sealing performance, so it is generally used for sealing gas or liquid media with smaller flow rates and higher pressures. The needle valve type is suitable for use in combination with the pressure gauge. Generally, needle valves are made with threaded connections.

It is widely applied in fields such as chemical engineering, petrochemicals, petroleum, papermaking, mining, power, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal services, mechanical equipment matching, electronics industry, urban construction, etc
