Concentric Lug Butterfly Valve: Introduction & Application<\/p>\n\n\n\n

1. Basic Overview<\/h3>\n\n\n\n

First, concentric lug butterfly valves serve as cost-effective pipeline accessories.<\/p>\n\n\n\n

Unlike ordinary flange valves, they own built-in lugs on both valve sides.<\/p>\n\n\n\n

Therefore, they need no full flange assembly and simplify field installation.<\/p>\n\n\n\n

Besides, they fit new pipeline construction and old equipment renovation perfectly.<\/p>\n\n\n\n

2. Structural Features<\/h3>\n\n\n\n

Firstly, the stem, disc and valve body share one central axis.<\/p>\n\n\n\n

Thus, the whole structure stays simple, compact and failure-resistant.<\/p>\n\n\n\n

Meanwhile, daily maintenance takes almost no extra time and cost.<\/p>\n\n\n\n

Also, the disc presses rubber seals to achieve stable sealing performance.<\/p>\n\n\n\n

Furthermore, it provides equal sealing effects for two-way medium flow.<\/p>\n\n\n\n

Hence, workers do not need to confirm fluid direction during installation.<\/p>\n\n\n\n

Moreover, it features low flow resistance and light opening and closing torque.<\/p>\n\n\n\n

In addition, it matches manual, electric and pneumatic driving modes.<\/p>\n\n\n\n

3. Unique Lug Installation Advantages<\/h3>\n\n\n\n

Specifically, lug structure is its biggest advantage over common wafer valves.<\/p>\n\n\n\n

Instead of double flanges, it fixes directly via lug hole bolts on site.<\/p>\n\n\n\n

Also, it supports pipe clamping and single-end blind sealing operations.<\/p>\n\n\n\n

Besides, it adapts well to pipe end installation and narrow working spaces.<\/p>\n\n\n\n

Therefore, it saves extra flange parts and shortens construction time.<\/p>\n\n\n\n

Meanwhile, its small occupation optimizes overall pipeline layout.<\/p>\n\n\n\n

4. Working Performance<\/h3>\n\n\n\n

Generally, soft-seal types achieve nearly zero leakage in daily work.<\/p>\n\n\n\n

However, it cannot adapt to ultra-high temperature and extreme pressure.<\/p>\n\n\n\n

Still, it works stably under 1.6MPa medium and low pressure conditions.<\/p>\n\n\n\n

Also, the valve owns light weight and mature integrated casting craft.<\/p>\n\n\n\n

Furthermore, it shows great cost advantages in bulk engineering purchases.<\/p>\n\n\n\n

5. Wide Application Scenarios<\/h3>\n\n\n\n

Primarily, it controls water and sewage for municipal water treatment plants.<\/p>\n\n\n\n

Besides, it serves circulating water systems for power and steel factories.<\/p>\n\n\n\n

Moreover, paper, food and chemical industries also widely adopt this valve.<\/p>\n\n\n\n

Meanwhile, it fits gas delivery, ventilation and building water pipelines.<\/p>\n\n\n\n

Additionally, it adjusts flow and cuts off pipelines for equipment maintenance.<\/p>\n\n\n\n

6. Product Summary<\/h3>\n\n\n\n

Overall, this valve has simple structures and mild usage requirements.<\/p>\n\n\n\n

Finally, flexible installation and stable sealing improve its practical value.<\/p>\n\n\n\n

Hence, it becomes a preferred choice for common low-pressure pipeline systems.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
