Product Description

Y-type forged steel check valve product overview:
"Y" type forged steel valve has three kinds of valve cover design form: the first is bolt type valve cover, according to this design form of the valve, the valve body and the valve cover are connected with bolts and nuts, winding gasket (316 clamp flexible graphite manufacturing) seal. When customers have special requirements, metal ring can also be used to connect. The second design form is welded valve cover, sweep this design form of the valve, the valve body and the valve cover with thread connection, internal pressure self-sealing ring seal.
Can be designed into a "Y" type valve has a globe valve and a check valve
