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.
