Lug Type VS Wafer Type Butterfly Valve

ZZJG Valve's wafer butterfly valves include wafer butterfly valve with handle, wafer butterfly valve with gearbox, electric wafer butterfly valve and pneumatic wafer butterfly valve. ZZJG Valve's lug type butterfly valves include lug butterfly valve with handle, lug butterfly valve with gearbox, electric lug butterfly valve and pneumatic lug butterfly valve.

Lug type butterfly valves and wafer type butterfly valves both belong to the butterfly valve category, with the primary difference lying in their connection methods. Wafer type butterfly valves use a clamping method to connect pipelines, while lug type butterfly valves connect pipelines via flanges.

The main features of wafer type butterfly valves include: a double clamping structure with uniform clamping force distribution and excellent sealing performance; a simple structure for easy installation; a compact design with lightweight construction, making them easy to handle and install.

The main features of lug type butterfly valves include: stable flange connections with a wide range of applications; excellent sealing performance and high-pressure resistance; convenient operation and ease of use.

The main difference between lug type butterfly valves and wafer type butterfly valves lies in their connection methods. Wafer type butterfly valves use a clamping method to connect pipelines, while lug type butterfly valves use flange connections. Due to the different connection methods, their installation methods also vary. Wafer type butterfly valves are typically installed using direct welding, socket welding, or flange connections. Lug type butterfly valves are typically installed using flange connections or socket connections.

Additionally, the sealing structures of the two types of valves also differ. The clamping structure of wafer type butterfly valves provides relatively better sealing performance, while lug type butterfly valves use sealing gaskets to ensure sealing performance.

In practical applications, lug type butterfly valves and wafer type butterfly valves each have their own advantages and disadvantages.

Wafer type butterfly valves have a simple structure, are easy to install, have a compact design, are lightweight, and are convenient to operate, making them suitable for small-scale pipeline systems or applications requiring frequent maintenance and replacement.

lug type butterfly valves, on the other hand, use flange connections, which provide more stable connections, making them suitable for medium to large-scale pipeline systems. In special applications involving high temperatures, high pressures, or highly corrosive media, lug type butterfly valves perform exceptionally well.

In summary, the main difference between flanged butterfly valves and wafer type butterfly valves lies in their connection methods. Each type of butterfly valve has its own applicable range and advantages or disadvantages in terms of application. When selecting a butterfly valve, factors such as applicability, installation convenience, ease of maintenance and replacement, pressure resistance, and corrosion resistance should be considered based on the specific application requirements.
