卡套式西德福高压球阀

西德福（Stauff）是德国的专业液压附件制造商，其高压球阀在业内享有盛誉。"卡套式"指的是阀门与管道之间采用卡套连接，这是一种通过拧紧螺母压迫卡套，实现管道与阀门之间紧密密封的连接方式。

卡套式西德福高压球阀这类阀门主要有以下特点：

· 连接方式：采用卡套连接，符合ISO8434-1/DIN 2353标准。

· 阀体材质：通常提供碳钢（表面常进行不含六价铬的锌镍镀层处理，耐腐蚀）和不锈钢（如V2A/-1.4305, V4A/-1.4571）等选项。

· 密封材料：标准密封材料一般为FPM（氟橡胶），也可根据介质特性选择NBR（丁腈橡胶） 或EPDM（三元乙丙橡胶） 等。

· 卡套式西德福高压球阀核心特点：

  · 浮动式球体设计，双向密封，泄漏等级符合严苛的EN12266 A级标准（试验时间内无可见泄漏）。

  · 阀座材料通常选用POM（聚甲醛）+ MOS2，耐磨且自润滑，寿命长。

  · 不锈钢球体经抛光处理，摩擦小，阀座磨损低。

  · 卡套式西德福高压球阀操作扭矩低，启闭方便。

· 工作压力：适用于高压环境，具体压力等级需看型号，部分超高压型号可达800 bar (约12,000 psi)。

· 卡套式西德福高压球阀温度范围：部分型号可适应-20°C 至 +100°C 的介质温度，特殊设计甚至能耐+500°C / +930°F 的高温。

· 适用介质：液压油、水、气体（包括压缩天然气CNG）、某些腐蚀性介质等。

German STAUFF Ferrule-Type High-Pressure Ball Valve Product Overview

Company Profile:

STAUFF is a German professional hydraulic accessory manufacturer, its high-pressure ball valves enjoy a high reputation in the industry . The "Ferrule-Type" ( Compression Fitting Type) refers to the valve being connected to the pipeline using ferrule connections. This is a sealing method achieved by tightening a nut that compresses the ferrule, creating a tight seal between the pipe  the valve .

Key Features & Technical Details:

· Connection Type: Utilizes ferrule connections complying with ISO8434-1/DIN 2353 standard .

· Body Material: Typically offered in Carbon Steel (often with a hexavalent chromium-free zinc-nickel coating for corrosion resistance)  Stainless Steel options (e.g., V2A/1.4305, V4A/1.4571) .

· Sealing Material: Standard sealing material is usually FPM (Fluorocarbon Rubber). Alternatives like NBR (Nitrile Butadiene Rubber)  EPDM (Ethylene Propylene Diene Monomer) can be selected based on media characteristics .

· Core Characteristics:

  · Floating ball design, providing bidirectional sealing. Leakage rate complies with the stringent EN12266 A standard (no visible leakage during test period) .

  · Seat material often POM (Polyoxymethylene) + MOS2, which is wear-resistant  self-lubricating, ensuring long service life .

  · Polished stainless steel ball reduces friction  seat wear .

  · Low operating torque, enabling easy operation .

· Working Pressure: Designed for high-pressure applications. Specific pressure ratings depend on the model, with some ultra-high-pressure models capable of up to 800 bar (approximately 12,000 psi) .

· Temperature Range: Certain models can handle media temperatures  -20°C to +100°C, with special designs resisting extreme temperatures up to +500°C / +930°F .

· Suitable Media: Hydraulic oil, water, gases (including Compressed Natural Gas - CNG), certain corrosive media, etc. .
