    What is a lug butterfly valve?

    The driving method of the lug butterfly valve can be used by manual, worm-gear, pneumatic, and electric. The connection method can be used for flanges and clamps. Structural forms can be used for single eccentric, middle line, double eccentric, triple eccentric. Seal structure can choose soft seal, hard seal, and the pressure range PN0.1-10Mpa. The nominal diameter is DN40 ~ 2000mm. The material can choose cast steel and stainless steel. Due to the extensive range of valves, the same valve has different combinations in different occasions and working conditions .
    The disc of the wafer lug butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc rotate around the axis, and the rotation angle is between 0°and 90°. When rotating to 90°, the valve is fully open.

    Advantages of the lug butterfly valve:
    1.Save place
    The length of the short structure can save raw materials and installation space. It can also effectively supports the strength of the pipe.
    2.Good sealing performance
    The squeezing speed of the disc can ensure that the valve is effectively sealed.
    3.Can meet the needs of various traffic
    According to the requirements of different working conditions, the design of V-shaped, triangular or pentagonal oil ports to meet the needs of various flow regulation.
    4.Epoxy resin layer
    Valves are epoxy coated with “zerk” type grease fitting for easy lubrication on neck and gear case (if applicable).

    Standard Test:

    Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.
    Seat Test: 1.1 times the working pressure with water.
    Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
    Special Test: On request, any other test can be carried out according to special instruction by client.
