Y-forged steel valve 
 A, Y type globe valve forged steel overview 
 Y-valve forged steel valve cover design in three forms. The first one is bolted bonnet, designed according to this design in the form of valve, the valve body and valve cover bolts nuts, spiral wound gasket (316 folders flexible graphite manufacturing) seal. Customers have special requirements can be used when the metal ring connections. The second design form is welded bonnet, designed according to this form of valve, the valve body and valve cover with a threaded connection, welded seal. Customers have special requirements can be welded when the second connection. The third type is the pressure from tight bonnet, designed according to this form of valve, the valve body and valve cover with a threaded connection, the internal pressure from the seal ring seal. Can be designed as "Y"-type valve cut-off valve and check valve. 

 Second, Y-type structure and characteristics of forged steel valve
