VALVE OPEN-SHUT INDICATOR
1157 CC
N3-22
The Oval Valve NPI45B10 (1157CC) is a valve open-shut indicator that forms part of a vessel’s control system. It shows whether an associated valve stands open or shut, giving operators and the wider control arrangement a clear view of valve status. The unit carries the model designation NPI45B10, the reference 1157 CC and the marking N3-22. It is supplied in used condition. Open-shut indication of this kind is part of valve monitoring on board, where knowing the position of individual valves supports routine operation of piping systems and the control station overseeing them.
