TechData
Diverting Valve
Three-Way Diverting Valves can be used for temperature
control in many heating and snowmelting applications.
Features
• Includes solder tailpieces (1-1/4" and 1-1/2" models use
same valve body with different tailpieces)
• Pre-installed high limit kit
• Compatible with most Viega actuators

Pressure Drop
Pressure drop values for Viega diverting valves may be
determined from the chart at right below. 1-1/4" and 1-1/2"
models share the same valve body, so the pressure drop for
these models is the same.
