Type 461 can be supplied in custom lengths and is available exclusively with threaded connections. The maximum centre-to-centre distance between the valves is 1500 mm.
Sealing is ensured by NBR seals integrated into the valves. In the event of contamination or malfunction, the indicator can be safely disconnected from the tank and drained via the integrated shut-off valves.
Due to the fragility of the glass tube, the Type 461 is supplied unassembled. During assembly, particularly for flanged versions, it is essential to ensure that the connections are precisely aligned and free from twisting, in order to avoid stress on the glass tube.
For additional protection against mechanical impacts during operation, a Plexiglas® protective tube is available as an optional extra.
