As we all know that the valve body like carbon steel (WCB, WCC, LCB, LF2, A105), stainless steel (SS304, SS316, F304L, F316L), hastelloy (Alloy 20) etc., or even in the trim material always use metallic materials. Most of the corrosion of metallic materials occurs in the atmosphere, which contains corrosive components and corrosive factors such as oxygen, humidity, temperature changes and pollutan...

Gate valves are available with a variety of disks. Classification of gate valves is usually made by the type disk used:Wedge type single gate valve,Resilient gate valve,Double gate type gate valve, or Parallel gate valve. 1）Wedge type single gate valve ①Simpler structure than resilient gate valve. (ii) At higher temperatures, the sealing performance is not as good as that of resilient gate valves ...

The emergence of the triple eccentric butterfly valve, or triple offset butterfly valve, has changed the stereotype of the butterfly valve. In the past, people usually thought that butterfly valves could only be used on ordinary pipelines at normal temperature and low pressure, and were not resistant to high temperature or high pressure. Buttriple eccentric butterfly valves have d...

When choosing valve products, purchasers should not only pay attention to which cryogenic ball valves can be trusted, but also pay more attention to the maintenance methods associated with the later application of the ball valves. After all, the valve is different from some other products. They are applied in many types of environment, likely to be affected by the conditions, such as sealing, loos...

Metal seated butterfly valve is that both sides of the seal are made of metal material or other hard materials. This seal has relatively poor sealing performance, but is resistant to high temperatures, abrasion and mechanical properties. Metal seated is often combined of such as: steel + steel, steel + copper, steel + graphite, steel + alloy steel. The steel here may also be cast iron, c...

Valves are control components in fluid transfer systems, with a variety of different functions such as stopping, regulating, diverting, preventing backflow, stabilizing pressure or overflowing pressure relief. Therefore, it can be used in many fields and has a wide range of uses. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurr...
