The excellent properties owned by full forging duplex stainless steel globe valve are determined by materials performances and valve structural features. Duplex stainless steel refers to ferrite and austenite inside solid solution account for half of proportion. So, duplex stainless steel combines high...
Nowadays, superhigh pressure technique has already been used for petrochemical industry, chemical industry, metal forming, powder metallurgy and other industries. Due to superhigh pressure technique widely applied, the performances of superhigh pressure valve have directly influenced on security, reliability,...
Oil lubrication hard seal plug valve can be classified into conventional oil lubrication plug valve and pressure balance plug valve. Tailor-made grease is injected between body and plug from top of plug, forming oil film to reduce torque of valve, highly improving sealing and service life. Conventional...
Check valves applied on sewage lifter can solve the problems which are caused by sewage backflow. Drain pipes equipped with check valves can protect equipment from being damaged by sewage backflow, and reduce water storage capacity inside equipment meanwhile. Sewage lifter is used to drain the...
For long service life, good rust resistance, environmental protection, stainless steel valves have been widely applied in industry. Stainless steel valves are one of valve products essential for pipes. However, there are still quite few manufacturers in China which can meet the international standards....
Check valve at the outlet of centrifugal pump is used to prevent water hammer caused fluid backflow in outlet pipeline from damaging impeller inside pump. Check valve is mainly used to prevent fluid from flowing back which makes pump reverse and cause damage. And it also protects other storage tanks...
In recent years, for global gas industry highly developing, LNG has already become an important part of international gas trade. By 2020, LNG will account for 40% of gas trade volume and 15% of gas consumption. Gas liquefying plant should be equipped with low temperature ball valve. So, the valve is...
For energy conservation, noise reduction, low fluid resistance, rapid on-off, axial flow check valve has been widely used for oil and gas transmission pipeline. In China, for large LNG terminals having been built or under construction, axial flow check valve is installed at the position where non-return...
Power station welding gate valve is used for pipes of high temperature high pressure water, oil or over-heating steam in thermal power plant, petrochemical industry and metallurgy. The valve has the advantages of wearing resistance, temperature resistance, corrosion resistance and long service life....
Hard seal eccentric semi-ball valve uses the common path of eccentric body, eccentric ball, seat and stem for centring when they make rotational motion. It is tighter during closing to realize sealing. The ball is separated from seat completely, eliminating the abrasion of sealing ring and overcoming...
