ValVE DiMEnsiOns
Motorized Valves should be sized by Cv ratings
(the capacity factor or flow coefficient). This is
defined as the number of gallons of water at 60°F
that pass through a device with a one pound per
square inch pressure differential.

• Make sure that the valve is installed on a horizontal pipe.
• Make sure that no condensate will drain back against the valve when closed. This will cause the steam to flash the
condensate causing the banging when the valve opens.
actuator does not move.
• Make sure that the control is sending a moving signal to the actuator. The control must have a relay in each of the
outputs.
• Check that the transformer is operating properly and is its VA rating is equal to or higher than the actuator's VA
