    Product Advantage

    General purpose lug butterfly valve manufactured according to EN 593. Wide range of standard materials available for various applications.

    This type of lug butterfly valve is equipped with soft replaceable seat, the tongue and groove seat design locks the seat in place and gives the butterfly valve dead end capability

    -The lug butterfly valve disc has two-way bearings, good sealing and no leakage during pressure test.

    -The flow curve tends to be straight. Excellent adjustment performance.

    -Center plate structure, small opening and closing torque

    -Long service elevator. Withstand the test of thousands of openings and closing operations.

    -Seat test: water at 1.1 times the working pressure to ensure bubble free closure..

    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.
