Soft Seal Lug Butterfly Valve GGG40 Handle Operation

Compared to wafer butterfly valves, lug butterfly valves have stronger connection stability, are less affected by pipeline flange parallelism and uneven bolt tension, and have higher sealing reliability; Compared to flange butterfly valves, the axial length is shortened by 30%~50%, the volume is more compact, the weight is reduced by 20%~40%, and installation space and transportation costs are saved.

1. Outstanding convenience in installation and maintenance: The protruding ear connection allows for independent disassembly of valves without the need to dismantle upstream and downstream pipelines. During maintenance, it does not affect the operation of the entire pipeline system, significantly reducing downtime; Compact in size compared to flange butterfly valves, suitable for scenarios with dense pipelines and narrow installation spaces.

2. Stable connection and reliable sealing: The protruding ears are directly bolted to the pipeline flange, ensuring even force distribution and avoiding sealing failure caused by uneven clamping force in the butterfly valve; Bidirectional sealing design, no restrictions on import and export directions, suitable for pipeline systems with bidirectional flow of media.

3. High strength and wide adaptability: The protruding ear structure of the valve body enhances the overall rigidity and can withstand higher pipeline pressure and medium pressure difference. The conventional pressure rating covers PN1.0~PN6.4MPa (some high-pressure models can reach PN10.0MPa), and the diameter covers DN50~DN2000, suitable for medium low pressure to medium high pressure, medium small to large diameter working conditions.

4. Flexible and diverse driving modes: can be matched with handles (small caliber, medium low pressure), turbines (large caliber, high pressure difference, with self-locking function), pneumatic (fast opening and closing, adapted to automation systems), electric (remote control, precise control) and other driving modes to meet the needs of different scenarios such as manual operation, automatic control, and unmanned operation.

5. Balanced cost-effectiveness: Compared to flange butterfly valves, the manufacturing and installation costs are lower; Compared to butterfly valves, the sealing reliability and structural strength are higher, making it a compromise between "economy" and "reliability".

Standard export wooden case packaging

The lug butterfly valve is suitable for pipelines in petroleum, chemical, food, pharmaceutical, papermaking, hydropower, ships, water supply and drainage, smelting, energy and other systems. It can be used as a regulating and shut-off device on various corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipes and containers.
