API Standard Titanium B367 Gr.C-2 Flanged Swing Check Valve

The swing type titanium check valve is a valve that can automatically prevent fluid backflow. Under the action of fluid pressure, the valve opens and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the outlet side pressure, the valve disc automatically closes under the influence of factors such as the gravity of the fluid pressure difference itself to prevent fluid backflow.

    product details

    Titanium and titanium alloys are highly chemically active metals that are non ferrous. Titanium materials have an oxide film, which provides good stability and self passivation ability in highly corrosive environments. Therefore, titanium valves can resist various harsh corrosion conditions. Titanium check valves have high corrosion resistance and are used in various highly corrosive media. Titanium check valves solve the corrosion resistance problem in industrial transportation pipelines that ordinary stainless steel check valves cannot solve. Titanium check valves have excellent corrosion resistance, high strength, light weight, hard and smooth surface, limited foreign object adhesion, and heat resistance.

    The selection of titanium check valves must fully consider four aspects: the temperature of the corrosive medium, the composition of the medium, the density of various components, and the water content. This valve is not suitable for conditions such as 98% red smoke nitric acid, 1.5% anhydrous dry chlorine, pure oxygen, and temperatures exceeding 330 ℃.

    Additional Features

    A swing check valve, also known as a one-way valve or check valve, is designed to prevent the backflow of medium in the pipeline. The valve that relies on the flow and force of the medium to open or close itself, in order to prevent the backflow of the medium, is called a check valve. Check valves belong to the automatic valve category and are mainly used in pipelines with unidirectional flow of medium. They only allow medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in pipelines. The swing check has two main characteristics:

    1. The selection of materials is meticulous, in accordance with relevant domestic and foreign standards, and the overall quality of the materials is high.

    2. The sealing pair is advanced and reasonable, and the sealing surfaces of the valve disc and valve seat are made of iron-based alloy or Stellite cobalt based hard alloy overlay welding surface, which is wear-resistant, heat-resistant, corrosion-resistant, scratch resistant, and has a long service life.

    Applications

    Rotary titanium check valves are widely used in industries such as power plants, chemical engineering, and hydraulic engineering. Whether they can resist corrosion from working environment media depends on the chemical stability of the "passive oxide film" on their surface in corrosive media. For neutral, oxidizing, and weakly reducing media environments, passive oxide films themselves have good stability.
