The bonnet is the key part of the whole valve structure. It is the cover plate of the valve body opening. It is connected with the valve body through threads, bolts or welded joints. Its main function is to lift the valve body, seal and keep the pressure from leaking.
Like valve bodies, bonnets are also designed in different shapes and sizes. Typically, our foundries cast material is stainless steel. In terms of material, it has the same casting material as the valve body. Stainless steel bonnet resists corrosion.
