Product DescriptionH41Y Flange forged steel check valve has
three valve cover design forms: the first is a bolt-type valve
cover. For valves designed according to this design form, the valve
body and the valve cover are connected with bolts and nuts, and the
wound gasket (316 clamp Made of flexible graphite) seal, metal ring
connection can also be used when customers have special
requirements. The second design form is a welded valve cover, in
which the valve body and the valve cover are connected with threads
and sealed by an internal pressure self-sealing ring. Forged steel
check valve refers to a valve that relies on the flow of the medium
itself to automatically open and close the valve disc to prevent
the backflow of the medium. It is also called a check valve, a
one-way valve, and a back pressure valve.Product Specification1.
