Worm Gear DI Body Lug Type Butterfly Valve

Worm Gear also called gearbox or hand wheel in butterfly valve. Ductile Iron body lug type butterfly valve with worm gear is common used in water valve for pipe. From DN40-DN1200 even larger lug type butterfly valve, we also can use the worm gear to open and close the butterfly valve. Ductile Iron body is suitable for a wide range of medium.Such as water, wast water,oil and etc.

    Product Advantage

    Small size, light weight and easy maintenance. It can be installed wherever needed.

    Simple and compact structure, 90-degree quick switch operation.

    The flanged 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.

    Can be used to cut and condition media.

    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.
