GVB/GVB12 Series Snap-Acting Relays
Brand: ITT ConoflowDesigned for pneumatic systems, Conoflow Series GVB 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.
- Divert flow or pressure from one device to another.
- The Series GVB Snap-Acting Relays have an integral pilot which eliminates the extra piping and connections required with other lock-up valves.
- Compact and lightweight, the relays are easily piped and mounted.
