Conoflow GVB11, GVB12 Snap-Acting Relays

The Conoflow GVB Snap Acting Relay series delivers essential protection and control for critical pneumatic systems. These innovative relays automatically switch or lock in secondary air sources when main supply pressure drops below preset thresholds, ensuring system reliability and continuous operation.

Available in GVB11 and GVB12 models, these snap-acting relays feature an integrated pilot design that eliminates additional piping and connections typically required with standard lock-up valves. The GVB12 offers enhanced capability with dual spool sections mounted in tandem for more complex applications.

Key Features of the Conoflow GVB Snap Acting Relay:

• Adjustable actuation pressure: 25-85 PSI (172-586 kPa)
• Maximum relay valve pressure: 150 PSI (1034 kPa)
• Precise 3/16″ valve port diameter (Cv 0.38)
• Compact, lightweight design for easy installation
• Durable construction with aluminum body and stainless steel components
• Operating temperature range: 0°F to +150°F (-18°C to +66°C)

Perfect for applications requiring automatic switching between main and auxiliary supply pressure, actuator position locking, or pressure diversion between devices. The Conoflow GVB Series represents the ideal solution for reliable pneumatic system protection and control.
