The Difference Between A Lug and Wafer Butterfly Valve

2019-02-12 16:59:28

Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.

Wafer type butterfly valve installation instructions and steps

2019-01-03 16:27:13

The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.

Product Details

Role in Valve Installation and Pipeline Maintenance

Dismantling joints are essential components in water transmission and wastewater pipeline systems, particularly where large-diameter valves are installed. Their primary function is to provide axial adjustment during installation and to create sufficient clearance for valve removal during maintenance.

In practical pipeline projects, dismantling joints help compensate for dimensional tolerances and simplify on-site alignment, reducing installation difficulty and labor intensity.

Application with Large-Diameter Valves

Dismantling joints are commonly installed together with butterfly valves, gate valves, and swing check valves in water pipeline systems. When used in combination with double eccentric butterfly valves, dismantling joints significantly improve installation efficiency and maintenance accessibility.

This combination allows valves to be removed without disturbing adjacent pipe sections, reducing maintenance time and minimizing operational disruption.

Engineering Benefits in Water Pipeline Systems

From an engineering perspective, the use of dismantling joints contributes to:

Improved installation flexibility
Reduced mechanical stress on valves and flanged connections
Shorter maintenance downtime
Enhanced safety during valve handling and replacement

For long-distance water transmission pipelines and underground valve chambers, dismantling joints are considered a standard and practical solution.
