ITT Conoflow GVB11, GVB12 Snap-Acting Relays
The ITT Conoflow GVB11 and GVB12 Snap-Acting Relays are lightweight, compact, and are easily piped and mounted. These snap-acting relays change ports to switch or lock in secondary air source when the main supply pressure fails below a predetermined set point. In the event of supply or pilot pressure failure, the positive action relay with one common, and two inlet or outlet ports will automatically switch from main to auxiliary supply pressure, lock an actuator in its last position, extend or retract an actuator stem, and divert flow or pressure from one device to another. The GVB11 and GVB12 snap-acting relays have an integral pilot which eliminates the extra piping, and connections required with other lock-up valves.
