Frequently Asked Questions
What is the difference between wafer and lug butterfly valves?
Wafer valves are clamped between two flanges; lug valves have threaded lugs and can also be used at line ends.
What does an air valve do?
It releases air from the pipeline and prevents vacuum when the line drains.
