1、 Overview of j11y forged steel stop valve:

API forged steel stop valve | j11y forged steel stop valve has three bonnet design forms The first is the bolted bonnet. For the valve designed according to this design form, the valve body and bonnet are connected with bolts and nuts, and the spiral wound gasket (made of 316 clip flexible graphite) is sealed. When customers have special requirements, metal rings can also be used for connection The second design form is the Welded Bonnet. According to this design form of valve, the valve body and bonnet are connected by thread and sealed by full welding. When customers have special requirements, through welding connection can also be used The third is the self sealing bonnet. For the valve designed according to this design form, the valve body and bonnet are connected by threads, and the internal pressure self sealing ring is sealed
