Series CSD
Calibrated Flow Measurement and
Balancing Valve
Sizes:
1
⁄2" – 2"
Series iDROSET CSD calibrated flow measuring and static
balancing valves are designed for hydronic heating and cooling
systems. With patented flow measurement technology inte-
grated into the valve, their large easy-to-read flow gauge and
hand wheel allow the continuous reading of flow and the setting
of flow without tools or additional instrumentation. The iDRO-
SET CSD’s ball-type design provides up to a 25:1 turn-down
ratio, positive shut-off and hand wheel locking screw to secure
adjustment.
The iDROSET CSD series is available with F-NPT connections
from ½" up to 2" with flow rate capability up to 7 GPM.
Features
• Patented integrated flow measurement technology factory
calibrated to +/- 10% accuracy
• Large gauge for easy reading of flow
• Lockable, gauge-integrated hand wheel for setting flow
• Ball valve design with positive shutoff
