Bell & Gossett Zone Controls & Parts

Snap Zone Valves

The Bell & Gossett Snap Zone Valve is an on/off zone valve for residential and light commercial use. Snap Zone valves are precision-engineered four-wire thermoelectrically operated valves designed for heating and cooling systems.

The valve opens and closes based on the voltages applied to the actuator. The actuator can be installed or removed at any angle on the adapter ring. The compact design and universality in the actuator mounting position allows for easy installation in the most difficult positions.

Snap Zone Valve Features:

• Soft close technology suppresses water hammer
• Silent actuator operation
• Internal components can be removed without having to remove units from the system
• 360° actuator installation
• One-handed actuator installation
