B&g circuit setter balance valve

In this Service Tip of the Month, we will be discussing and demonstrating the operation of reading, adjusting, and setting a Bell & Gossett Balance Valve. The example we are using today is a manual balance valve across a heating coil.

The Bell & Gossett (B&G) balance valve was found to be in the 100% open position.

The coil associated with the B&G balance valve was loud (velocity noise) and had difficulty maintaining the condition space. We found the blueprints to the building and quickly discovered the required design flow for this heating coil was 11GPM.

This became the catalyst we needed to read the flow, adjust the B&G Circuit setter, and set the valve to the design flow of 11GPM.

Setting a Bell & Gossett Balance Valve

We will need a few industry tools to walk through this exercise. We will need a Bell & Gossett RO-1-60 readout meter. All readout kits feature a compound gauge that
