Protocol Switchover Station

5029 Protocol Switchover Station
The 5029 Series Protocol Switchover Station combines all of the
safety and convenience features of a standard Protocol Station with
the added efficiency of having a reserve cylinder connected to the
system. The Protocol Switchover Station valving allows manual
switching between a primary cylinder and reserve cylinder. Isolation
of the depleted cylinder allows safe changeout without back flow
of gas through the pigtail.
Protocol Switchover Stations are available in brass or 316 stainless
steel with a variety of pressure ranges (3,000 psig, 4,500 psig and
6,000 psig). The system comes complete with a Protocol Station,
two 3-foot tall stainless steel pigtails with armor casing, two 1/4 turn
diaphragm valves (3,000 psig) or needle (4,500 or 6,000 psig).
Alarms are also available for the Protocol Switchover Station.
