Other Products
I. Introduction:
The J61Y forged steel welded globe valve has three bonnet design forms. The first is a bolted bonnet. For valves of this design, the valve body and bonnet are connected by bolts and nuts, with a spiral wound gasket for sealing. A metal ring connection can also be adopted if the customer has special requirements. The second design form is a welded bonnet. For valves of this design, the valve body and bonnet are connected by threads, with full welding for sealing. A full penetration welding connection can also be adopted if the customer has special requirements. The third is a self-sealing bonnet. The J61Y forged steel welded globe valve is suitable for pipelines in various working conditions such as petroleum, chemical industry, and thermal power plants with ANSI Class1500～2500Lb and operating temperature ranging from -29℃ to 570℃, to cut off or connect the medium. The applicable media are water, steam, etc. The operation modes include manual, gear transmission, electric drive, etc.
