If you require a durable butterfly valve that can withstand high pressures and temperatures

If you require a durable butterfly valve that can withstand high pressures and temperatures, the lug-style butterfly valve may be your perfect solution. Its tight seal can prevent leaks while handling larger velocities than wafer styles - but to select the appropriate valve it's important to understand their differences to select the optimal choice for your application.

Lug butterfly valves feature long circular bodies, round disk and shaft assemblies, and metal or resilient seats and are capable of both isolation and light control/throttling services, making them an excellent option in applications with limited space where traditional valves may be impractical.

While lug-style butterfly valves provide many advantages, they do have some drawbacks as well. They tend to be more expensive than their wafer counterparts and need to be installed properly or they risk becoming damaged or losing effectiveness.

For your own protection, always seek the services of a professional to install your valves properly. They will ensure the valve is placed correctly and securely mounted to pipe flanges; additionally, they can help determine whether lug-style or wafer-style valves would best meet your needs; providing insight into their advantages and disadvantages as they explain these options to you.

A lug-style butterfly valve can be identified by its distinctive threaded "ears", located around its entire perimeter and fitted with threads tapped from threading machines. These ears have been designed so they correspond with holes found on flanges connecting pipes for easier installation and alignment - and allow the butterfly valve to be secured to each flange with 2 separate bolts so there will be no relaxation from thermal expansion.

A key advantage of the lug-style butterfly valve is that it can be disconnected from one side of a system without disrupting another side, thanks to threaded inserts, flanges and two sets of bolts (lugs) per flange that don't require nuts for their attachment - enabling easy cleaning, inspection, repair or replacement without shutting down entire systems.

Both types of butterfly valves offer their own set of advantages and disadvantages but are nonetheless excellent options for various applications. When selected properly and installed professionally and maintained accordingly, they can provide years of reliable service that maximizes your piping system's potential.
