Forged Globe Valve

One of the two major components of forging.The mechanical properties of forgings are generally better than those of castings of the same material.In machinery, the important parts with high load and severe working conditions, except the simple shape of the available rolled sheet, profile or welding parts, are mostly forgings.Forging materials are mainly composed of carbon steel and alloy steel, followed by aluminum, magnesium, titanium, copper and other alloys.The raw materials include bar, ingot, metal powder and liquid metal.The ratio of the cross-sectional area of the metal before deformation to the area of the die after deformation is called forging ratio.It is very important to choose forging ratio correctly to improve product quality and reduce cost.Forged steel globe valves are designed and manufactured according to API 602 standard, and three kinds of bonnet design are provided: bolted bonnet, welded bonnet and pressure self-sealing bonnet. Users can choose different styles according to their needs, and provide RF flange, NPT thread and SW welded bonnet.Needle valve is a kind of small-caliber instrument valve, which plays the role of opening and closing and precise flow control in the instrument measurement pipeline system.
