Ductile iron soft seal non rising stem gate valve
About non rising stem gate valve: NRS means Non-Rising Stem. In an NRS valve, the stem will turn to open and close the gate, but the stem does not move up or down as it turns. With a OS& Y valve, as the stem turns, it moves into or out of the valve, which also moves the gate to open or seal the valve.
