Simple instructions for lug butterfly valve

 Author :Qingdao Fluido Industrial Co., Ltd

Lug butterfly valves, like other butterfly valves, are used to regulate and control the flow rate."Lug" is the lug on the valve body that can be used to connect flanges. The main components of the lug-type butterfly valve include the body, disc, stem, seat, and actuator. The valve body is usually made of cast iron, ductile iron, or stainless steel. The disc is attached to the stem and rotates inside the body to control the flow of the fluid. The seat provides a sealing surface for the disc to ensure tight closure when the valve is closed. The actuator can be manual, electric, or pneumatic to control the position of the disc.

The main feature of the lug butterfly valve is its versatility. It can be used in low-pressure and high-pressure applications and is suitable for a wide range of industries such as water treatment, oil, gas, chemical, and power generation. The lug design realized easy installation and disassembly without damaging the pipes and easy for maintenance and replacement.

The lug-type butterfly valve is easy to operate. When the valve is fully open, the disc is perpendicular to the fluid allowing maximum flow. When the valve is closed, the disc rotates to a parallel position, gradually reducing the flow rate until it is fully closed. The valve can minimize the pressure drop on the valve, which can save energy and improve efficiency.

Similar to the lug-type butterfly valve, the wafer-type butterfly valve is often be mentioned. The wafer-type structure is simpler, usually, only four centering ears on the body, the bolts to connect the flange passes through the valve-centering ears, the valve is sandwiched between the two flanges. Relatively speaking, the lug type is more stable, and the wafer type is more convenient and cheaper. They are suitable for different occasions and can be selected according to different needs.
