LUG BUTTERFLY VALVES

VALVES-BUTTERFLY-VALVES-LUG-BUTTERFLY-VALVES

Overview

LUG-STYLE STAINLESS STEEL BUTTERFLY VALVES feature threaded bolt holes that allow removal of downstream piping without shutting down the entire system. This makes lug valves ideal for dead-end service, isolation points, and systems requiring maintenance flexibility.

Ace supplies stainless steel lug valves engineered for higher structural loading, refined torque characteristics, and robust performance in industrial water, chemical, and utility service.
