仿进口卡套针阀

“仿进口卡套针阀”是指中国国内制造商参照或模仿国外（如欧洲、美国、日本等）知名品牌的设计、技术和标准所生产的卡套式针形截止阀。这类产品通常在性能和质量上力求接近或达到原装进口产品的水平，但具有更具竞争力的价格和更快的交货周期，是进口产品的一种经济型替代方案。

仿进口卡套针阀主要特点：

· 仿进口卡套针阀设计新锐：仿照进口产品的成熟设计，具有结构紧凑、密封性能好、使用寿命长等特点。

· 仿进口卡套针阀精密控制：采用螺旋升降的阀杆和细长的针状阀芯，可以实现对流体流量的精准微调。

· 仿进口卡套针阀密封稳定：通常采用金属密封或PTFE密封，确保在高压环境下仍能实现零泄漏。

· 多种连接：核心为卡套式连接，安装简便，仅需扳手拧紧螺母即可完成密封，适用于仪表、液压、气动等管路系统。

· 材料多样：阀体材料通常为不锈钢（如304、316），也提供碳钢、黄铜等，以适应不同介质（水、油、气及某些腐蚀性介质）和工况要求。

仿进口卡套针阀典型技术参数：

· 公称通径：通常为DN6、DN8、DN10、DN15等（或对应1/4"、3/8"、1/2"等英制规格）。

· 压力范围：PN25、PN40或更高，常见工作压力可达3000PSI、6000PSI甚至10000PSI。

· 温度范围：根据密封材料不同，通常为 -20℃ ~ 230℃。

· 适用介质：油、水、气、以及多种腐蚀性化学介质。

仿进口卡套针阀应用领域：

广泛应用于石油化工、仪器仪表、电力、半导体设备、实验室装置、液压系统、空分设备等需要精准流量控制切断的工业领域。

核心定位 以国产价格提供接近进口品质的产品，是进口阀门的高性价比替代品。

关键优势 价格优势、交货快捷、技术服务响应迅速。

技术基础 基于成熟且经过市场验证的进口产品设计与标准。

选购建议 在选择时，应重点关注制造商的工艺水平、质量控制体系和材料认证（如材质报告），以确保产品满足具体的应用需求。

Domestically Produced Import-Style Ferrule Needle Valve Product Overview

Product Definition:

"Domestically Produced Import-Style Ferrule Needle Valves"refer to ferrule-type needle shut-off valves manufactured by Chinese domestic producers. These products are designed by referencing replicating the technologies, designs, standards of well-known foreign brands (e.g., Europe, the USA, Japan). They aim to achieve performance quality levels close to on par with genuine imported original products, while offering a more competitive price shorter delivery lead times. They serve as a cost-effective alternative to imported valves.

Key Features:

· Advanced Design: Based on the proven designs of imported products, featuring a compact structure, excellent sealing performance, long service life.

· Precise Control: Utilizes a spirally actuated stem a long, tapered needle-point plunger, allowing for fine metering precise adjustment of fluid flow.

· Reliable Sealing: Typically employs metal-to-metal PTFE seals, ensuring zero leakage even under high-pressure conditions.

· Versatile Connections: The core feature is the ferrule-type connection (also known as a compression fitting). Installation is simple – sealing is achieved by tightening the nut with a wrench, making it ideal for instrumentation, hydraulic, pneumatic tubing systems.

· Diverse Materials: Body materials are commonly stainless steel (e.g., SS304, SS316), with carbon steel brass also available. This variety accommodates different media (water, oil, gas, certain corrosive chemicals) application requirements.

Typical Technical Parameters:

· Nominal Diameter: Typically DN6, DN8, DN10, DN15, etc. ( corresponding Imperial sizes like 1/4", 3/8", 1/2").

· Pressure Rating: PN25, PN40, higher. Common working pressures can reach 3000 PSI, 6000 PSI, even 10000 PSI.

· Temperature Range: Depending on the seal material, typically -20℃ to 230℃.

· Applicable Media: Oil, water, gas, various corrosive chemical media.

Application Fields:

Widely used in industries requiring precise flow control reliable shut-off,such as:

· Petrochemicals

· Instrumentation & Process Control

· Power Generation

· Semiconductor Manufacturing Equipment

· Laboratory Apparatus

· Hydraulic Systems

· Air Separation Plants
