    Product Details

    Lug butterfly valve is suitable for applications where the valve needs to be installed between two flanges. The valve is designed with lugs that allow it to be bolted onto the flanges, providing a secure connection. The another type-wafer butterfly valve is suitable for applications where the valve needs to be installed between two pipes. The valve is designed with a wafer that allows it to be sandwiched between the pipes, providing a tight seal. 

    In several common connection ways of butterfly valves, the price of wafer type is the cheapest, followed by lug type butterfly valve, flange type butterfly valve is the most expensive, the price is proportional to the overall weight.

    Key Features

    Anti-Blow Out Stem    
    Bi-Directional    
    Fire safe Design    
    Low Friction Body Seat

    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.
