      鑫盛源法兰针型阀针型阀优点：

      1、两截阀杆设计，上阀杆螺纹淡化工艺处理

      2、下阀杆表经经滚压硬化处理上阀杆螺纹的润滑脂与系统介质隔离

      3、无旋转的下阀杆垂直运动代替旋转升降，减少阀杆行程对填料的磨擦，手感更轻便

      4、阀门在全开位置具有背密封功能

      5、可安装手柄或者手轮操作，稳固耐用多种颜色手柄可供选择

      6、每只阀门在出厂前均按设计压力的1.1倍进行氮气密封测试,并按额定工作压力的1.5倍水压进行壳体强度测试

法兰针型阀

法兰针型阀是一种采用法兰连接方式的针型阀，主要用于对流体流量进行精密调节和截断，适用于高压、小流量的气体或液体介质管路系统。

法兰针型阀阀芯呈针状，与阀座精密配合，密封性能好，能有效防止介质泄漏，确保截断和调节的稳定性。法兰连接通过螺栓紧固阀体与管道的法兰面，连接牢固且耐压能力强，便于安装拆卸和维护，尤其适合中高压、大口径或需要频繁检修的工况。阀体材质多选用碳钢、不锈钢（如304、316）等，可适应水、蒸汽、油品及部分腐蚀性介质，工作压力通常可达32MPa，工作温度范围根据材质不同约为-40℃至540℃，广泛应用于石油、化工、电力、冶金等行业的高压管道系统中。

The flange needle valve is a type of needle valve with flange connection, mainly used for precise regulation shut-off of fluid flow, suitable for high-pressure, small-flow gas liquid medium pipeline systems.

Its valve core is needle-shaped, fitting precisely with the valve seat, which provides excellent sealing performance can effectively prevent medium leakage, ensuring the reliability of shut-off regulation. The flange connection fastens the flange faces of the valve body pipeline through bolts, featuring firm connection, strong pressure resistance, convenient installation, disassembly maintenance. It is especially suitable for medium-high pressure, large-diameter working conditions requiring frequent overhaul. The valve body is mostly made of carbon steel, stainless steel (e.g., 304, 316), etc., adaptable to water, steam, oil products some corrosive media. The working pressure can usually reach 32MPa, the working temperature range is approximately -40℃ to 540℃ depending on the material. It is widely used in high-pressure pipeline systems in industries such as petroleum, chemical industry, electric power, metallurgy.
