Oxygen globe valve is one of the special valves for oxygen pipeline network. It not only has the function of ordinary globe valve, but also has the characteristics of good flame retardancy, good conductivity, fast heat transfer, compact structure, oil proof, safety and reliability. With the development of metallurgical industry, oxygen globe valve and oxygen ball valve are widely used in iron and steel, metallurgy, medicine, chemical industry and so on.
1 BALL VALVES
Ball valves shall be provided with the following:
• Lockable device (opened and closed).
• Blow-out proof stem.

مزورة الصلب الصمامات العالم وأساسا لوقف أو ربط المتوسطة في خطوط الأنابيب على أنظمة مختلفة من محطة للطاقة الحرارية، وخاصة بالنسبة للغير قابلة للتآكل وسائل مثل الماء والبخار. مقارنة الصمامات الأخرى، وصمامات مصنوعة من الفولاذ المقوى هي من نسيج ج haracterized إغلاق، أداء أفضل المادية، يعني ذلك ارتفاع درجات الحرارة والضغوط العالية.
Válvulas globo em aço forjado são principalmente o fornecimento de parar ou ligar o meio de nos oleodutos em vários sistemas de estação de energia térmica, especialmente para não corrosivos mídias como água e vapor. Comparado com outras válvulas, válvulas de aço forjado são c haracterized pela textura perto, melhor desempenho físico, isso significa temperaturas, altas pressões.

A valve with a bellows to seal off the stem enclosure is an ideal choice whenever leakage to the atmosphere is intolerable due to toxicity, chemical corrosion, radioactivity, other health or ecological reasons. In addition, seal welding the body-bonnet seal makes the valve hermetically sealed. The bellows is welded to the stem and to the bottom of the bonnet.
Supplier: Sangong Valve, China
Manufacturer: Shop in Wenzhou Oubei Industrial Park
Bellow seal valve is designed with bellow welded onto the bonnet and stem, so that when the stem travels drive the below expansion or decompression. It inherently eliminate the conventional design of possible stem packing leakage. SGV bellow sealed valves can achieve truly zero leakage; ideal for stringent leakage-free application like toxic and flammable services. Bellow seal valve is an ideal choice whenever leakage to the atmosphere is intolerable due to toxicity, chemical corrosion, radioactivity, other health or ecological reasons. In addition, seal welding the body-bonnet seal makes the valve hermetically sealed. Continue reading “Bellow Seal Valves:Gate,Globe Valve”
8.1 Valves shall comply with the relevant standards and codes as specified herein and in the valve data sheets.
2 Ball Valves
All ball valves shall be of a fire tested design to BS6755 Pt 2, API 6FA or API 607,certified accordingly and fitted with fire safe seals.
Valves shall be of anti-static design with blow out proof stems.
The design of all ball valves shall incorporate body cavity pressure relief, which shall be achieved through seat design. A hole drilled in the ball to achieve body cavity relief is not acceptable.
Ball valves shall be reduced bore pattern, unless otherwise specified full bore on the individual data sheets. Reduced bores shall be limited to one line size smaller than body size.
This vacuum valve is mainly used in heat-engine plant’s vacuum minus pressure and condensation system, Petrochemical, Pharmaceuticals and other industry’s negative pressure condensation system. as a open-close and separation device.
