Application / Purpose:
In addition to sharing the advantages of non-rising stem resilient seated gate valves, the rising stem resilient seated gate valve provides a direct, visual indication of the valve position (open/closed). Featuring fast, reliable operation, it is widely used in fire protection and industrial systems, and is typically installed at higher elevations above the ground.
