Casting Iron Body CF8 Disc Lug Type Butterfly Valve

A lug type butterfly valve refers to the way the valve is connected to the piping system. In a lug type valve, the valve has lugs (projections) that are used to bolt the valve in between flanges. This design allows for easy installation and removal of the valve.

    Product Advantage


    • Casting Iron Body: This suggests that the body of the valve is made of cast iron. Cast iron is a common material used in industrial valves due to its strength and durability.
    • CF8 Disc: CF8 is a designation for a type of stainless steel. The term "CF8 Disc" indicates that the disc (or the butterfly element of the valve) is made of CF8 stainless steel. CF8 is known for its corrosion resistance and suitability for valve applications.

     Following is the QC test standard.

    Body test: 1.5 times the working pressure of water. The test is carried out after the valve is assembled, and the valve disc is in the half-open position, which is called the valve body hydraulic test.

    Seat test: water at 1.1 times the working pressure.

    Functional/Operational Test: At final inspection, each valve and its actuator (flow lever/gear/pneumatic actuator) undergo a complete operational test (open/close). The test is performed without pressure and at ambient temperature. It ensures proper operation of the valve/actuator assembly, including accessories such as solenoid valves, limit switches, air filter regulators, and more.

    The lug valve is mainly used for pipeline flow, pressure and temperature control in various industrial automation production, such as: electric power, petrochemical, metallurgy, environmental protection, energy management, fire protection system and butterfly valve sales.

    At the same time, the lug valve has good fluid control performance and is easy to operate.

    They are not only widely used in general industries such as petroleum, gas, chemical, water treatment, etc., but also in the cooling water system of thermal power plants.

    16 years valve manufacturing experience.
