  • What Are The Structural Characteristics of Fixed Ball Valve

    The fixed ball valve not have friction when open and close. This function solves the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces.

  • How Do Two-Way Diverter Valves Enhance Fluid Control Systems?

    Two-way diverter valves are essential components in fluid control systems, offering flexibility, efficiency, and reliability. Their ability to manage flow direction effectively makes them invaluable across various industries, from water treatment to HVAC and chemical processing.

  • Check valve installation method

    wing check valve: The disc of the swing check valve is disc-shaped and rotates around the rotating axis of the valve seat channel. Because the channel in the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for large-diameter occasions with low flow velocity and infrequent flow changes, but it is not suitable for pulsating flow, and its sealing performance is not as good as the lifting type.

  • Gate valve type

    There are many domestic manufacturers of gate valves, and most of the connection sizes are not uniform. Mainly divided into the following categories: 1. Standard valves produced by the Ministry of Machinery according to JB/T2203-1999 "Structure Length of Gate Valves"; 2. National standard valves produced according to GB/T12221-2005 "Structure Length of Metal Valves"; 3. American standard valves produced by ASME B16.10-2009 "Face-to-face and end-to-end dimensions of valves".

  • Knife Gate Valve Installation

    Before installing the valve, the user must check the valve model, connection size and pay attention to the flow direction of the medium to ensure consistency with the valve requirements.

  • How to use Globe Valve?
