Function

The balancing valve accurately controls the flow rate of heating and

cooling transfer fluid supplied to fan coils and terminal units; or where

flow balancing is required in solar thermal systems. Proper hydronic

system balancing ensures the system operates according to design

specifications, providing satisfactory thermal comfort with low energy

consumption.

The flow meter is housed in a bypass circuit on the valve body and

can be shut off during normal operation. The flow meter permits

fast and easy circuit balancing without added differential pressure

gages and charts. The balancing valve comes standard with a hot

pre-formed insulation shell to optimize thermal performance for both

hot and chilled water.

Flow rate adjustment The flow rate is adjusted by carrying out the following operations: A. With the aid of the indicator (1), mark the reference flow rate on which the valve is to be set. B. Use the ring (2) to slowly open the flow meter bypass valve that shuts off the flow of medium in the flow meter (3) under normal operating conditions. C.

D. After completing the balancing, release the ring (2) of the flow meter bypass valve, which will automatically go back into the closed position. 2 E. On completing the adjustment, the indicator (1) can be used to keep the setting in memory, in case checks need to be made over time. 1 F. A replacement flow meter bypass valve stem with operating ring is available in the event it is damaged and inoperable. Order code F19346. See page 6 for replacement instructions.

Procedure for installation and insulation assembly 1. Remove the protective strip from the adhesive surface. Re-close the insulation shells. Procedure for replacing bypass valve stem with operating ring 1. Remove bypass valve assembly with an 8 mm wrench. 2. If the balancing valve with flow meter is used with chilled water, spread a thin layer of sealant on the edge of the insulation and wait until the solvent evaporates (10 minutes approx.) and then re-close it. 2.
