Wafer VS Lug Butterfly Valve

When it comes to marine valves, two commonly used types are wafer and lug butterfly valves. Here’s a comparison of these valves in the context of marine applications:

  • Design:
    • Wafer Butterfly Valve: The wafer valve for marine applications has a compact and lightweight design. The butterfly wafer valve is positioned between flanges and secured using bolts and nuts. They do not have additional flange holes or lugs.
    • Lug Butterfly Valve: The lug-type marine valves feature threaded inserts on both sides, allowing them to be bolted to the pipeline using separate flange sets. They have protruding lugs that provide additional structural support.
  • Installation:
    • Wafer Butterfly Valve: Installing a wafer valve in marine systems is relatively straightforward. It require less space due to its compact design and are placed between flanges, which are then fastened using bolts and nuts.
    • Lug Butterfly Valve: For lug valves in marine applications, more space is needed due to the protruding lugs. These valves are attached to the pipeline by bolting them through the lug holes, providing enhanced stability and support.
  • Pressure Rating:
    • Wafer Butterfly Valve: Butterfly wafer valve typically has a lower pressure rating compared to lug valves in marine environments. As such, the wafer valve is suitable for applications with lower pressure requirements.
    • Lug Butterfly Valve: Lug-type marine valves are designed to handle higher pressure ratings, making them well-suited for marine applications that demand increased strength and durability.
  • Maintenance and Repair:
    • Wafer Butterfly Valve: Maintaining and repairing wafer valve in marine systems is generally easier due to its simpler design. It can be easily removed from the pipeline by detaching the bolts and nuts.
    • Lug Butterfly Valve: Lug valves may require more effort for maintenance and repair since they have additional flange sets and lugs. This means that the entire valve may need to be unbolted from the pipeline during servicing.
