A batch of 18-inch 904L (UNS N08904) wafer butterfly valves has passed final inspection and been shipped.
The 904L construction offers superior resistance to sulfuric acid and chlorides, far exceeding 316L performance. Its compact wafer design simplifies installation, while the precision-machined disc ensures reliable bi-directional bubble-tight sealing.
Featuring a robust one-piece stem and reinforced body, these valves withstand high mechanical stress during frequent cycling. Every unit undergoes rigorous pressure testing before leaving our factory.
NSV remains committed to delivering precision-engineered valves that support safe and efficient operations across global industrial pipelines.
