The U-Section Flanged Butterfly Valve Install on Pipe

The U-Section Flanged Butterfly Valve Install on Pipe
2026-08-05
Unlike a wafer valve that is merely "sandwiched" between flanges, the U-section flanged butterfly valve uses captive nuts housed inside the valve body's U-slot to engage fully threaded stud bolts. This allows the valve to be securely clamped to either pipe flange independently — delivering true dead-end service where one side of the pipeline can be disconnected while the other remains pressurized.

Wafer vs Lug vs Double Flange Butterfly Valve: Complete Design, Installation & Selection Guide

Wafer vs Lug vs Double Flange Butterfly Valve: Complete Design, Installation & Selection Guide
2026-08-04
Selecting the wrong butterfly valve body style can lead to installation headaches, leakage at the flange joint, or costly rework during plant shutdowns. This guide breaks down the structural differences, installation requirements, pressure limitations, and cost trade-offs between the three dominant butterfly valve body types — wafer, lug, and double flange — so you can specify the right valve for every piping application.

Wafer vs U-Section Butterfly Valve Installation: 5 Field Differences

Wafer vs U-Section Butterfly Valve Installation: 5 Field Differences
2026-07-29
Wafer butterfly valves use long through-studs to sandwich between pipe flanges — faster to install but prone to centering errors and incapable of dead-end service. U-section butterfly valves bolt directly into threaded flange holes on a U-shaped body, providing easier alignment, dead-end capability, and better support for plastic flanges, at a slightly higher cost.

Butterfly Valve Cv and Kv Values

Butterfly Valve Cv and Kv Values
2026-07-20
When selecting a butterfly valve for any application, understanding Cv and Kv values is essential. These flow coefficients determine how much fluid a valve can pass at a given pressure drop, directly impacting system performance, pump sizing, and energy efficiency.
