Products Name:Welding Check Valve
H61H, H61Y type 800 (Lb) socket welding forged steel check valve there are three kinds of body cover connection design. The first is a bonnet bonnet: A valve designed in this design has its body and bonnet bolted to a nut, and a wrap-around gasket (made of flexible graphite 316) is sealed. Customers can also use special metal ring connection. The second design is welded bonnet, according to this design of the valve, the valve body and the valve cap screwed, all-welded seal. Customers have special requirements can also be used when welding penetration. The third is self-tight pressure valve cover, according to the design of this design of the valve, the valve body and the valve cover threaded connection, the pressure from the ring seal.

The opening and closing parts are opened or closed by the medium flow and force to prevent the medium from flowing backwards to prevent accidents. The check valve is divided into structures according to the structure, and can be divided into three types: lift check valve, swing check valve and butterfly check valve. Lift check valves are available in both vertical and horizontal versions. The swing check valve is divided into three types: single-lobed, double-lobed, and multi-lobed. The butterfly check valve is straight-through type, and the above several check valves can be divided into three types: thread connection, flange connection and welding.
