operational principle: Stainless steel pneumatic ball valves have evolved from globe valves. It has the same 90 degree rotation lifting action, but the difference is that the plug body is a sphere with a circular through-hole or channel passing through its axis. The ratio between the sphere and the channel should be such that when the sphere rotate1
There are three types of valve cover designs for forged steel gate valves. The * type is a bolt type valve cover. Valves designed according to this design form have valve bodies and valve covers connected by bolts and nuts, and wound gaskets (made of 316 flexible graphite) sealed. When customers have special requirements, metal ring connections can1
Q41 forged steel high-pressure ball valve is mainly used for long-distance pipeline transportation of petroleum and natural gas, as well as urban gas pipeline systems. Due to the unique characteristics of valves used in long-distance pipelines, their ability to withstand pipeline stress, as well as safety, weather resistance, and long-term reliabil1
Vacuum check valve, also known as vacuum blocking valve, vacuum check valve, vacuum one-way valve, etc., is installed at the suction port of the vacuum pump to prevent the working fluid and air of the vacuum pump from flowing back to the vacuum system in case of pump shutdown or unexpected power outage, which may cause contamination of the working 1
Electric fluorine lined ball valves are mainly used in pipelines with various concentrations of strong alkaline organic solvents and other corrosive gases and liquid media. And it is suitable for conveying various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and various organic acids, strong acids, and strong o1
Pipeline flame arresters, also known as fire extinguishers, are designed to prevent external flames from entering equipment or pipelines containing flammable and explosive gases, or to prevent flames from spreading between equipment and pipelines. It is a safety device used to prevent the outward spread of hydrogen flames, composed of a solid mater1
Natural gas flame arresters are designed and manufactured based on the principle of extinguishing flames due to heat loss when they pass through narrow pores in thermal conductors. They are suitable for storage and flare systems of combustible gas pipelines, such as gasoline, kerosene, light diesel, benzene, methyl benzene, crude oil and other oil 1
