SS-6DBS12MM针阀

 SS-6DBS12MM针阀- 核心分类：归属飞托克6系列，为高压仪表针阀，采用棒料阀体结构提升强度与密封性。

SS-6DBS12MM针阀- 关键参数：阀体材质为316不锈钢（型号中“SS”代表Stainless Steel），连接方式为12毫米公制管承插焊（“12MM”标识），工作压力可达10000 psig（689 bar），工作温度范围-65°F至600°F（-54°C至316°C），填料多为PTFE或石墨，适配不同介质需求。

SS-6DBS12MM针阀- 核心设计：采用非旋转阀杆，减少填料磨损；具备全开位置背密封功能，支持在线维护；手柄为防误操作设计，部分型号可加锁，确保工况安全稳定。每台阀门出厂前均通过额定压力下的氮气或水压密封测试，符合工业仪表阀标准。

The SS-6DBS12MM needle valve is a 6-Series instrument needle valve manufactured by FITOK Corporation (USA), focusing on precise flow control under high-pressure working conditions, is widely used in petroleum, chemical other industrial fields.

 The SS-6DBS12MM needle valve- Core Classification: It belongs to FITOK's 6-Series, classified as a high-pressure instrument needle valve, with a bar stock valve body structure to enhance strength sealing performance.

The SS-6DBS12MM needle valve- Key Parameters: The valve body is made of 316 stainless steel (the "SS" in the model stands for Stainless Steel), with a connection method of 12mm metric tube socket weld (marked by "12MM"). Its working pressure can reach 10000 psig (689 bar), the working temperature range is -65°F to 600°F (-54°C to 316°C). The packing is mostly PTFE graphite, suitable for different medium requirements.

The SS-6DBS12MM needle valve- Core Design: It adopts a non-rotating valve stem to reduce packing wear; it has a back-sealing function in the fully open position, supporting on-line maintenance; the handle is designed for misoperation prevention, some models can be locked to ensure safe stable working conditions. Each valve undergoes a nitrogen water pressure sealing test under rated pressure before leaving the factory, complying with industrial instrument valve standards.
