1-1/2" FPT Caleffi Quicksetter Balancing Valve with Flow Meter & Insulating Shell
Specifications:
- Connection Size 1-1/2"
- Flow Rate Range - 8.0-32 GPM
- Heat Pump Nominal Tons (Closed Loop) - 3-10
- Heat Pump Nominal Tons (Open Loop) - 5-21
- Valve Cv- 32.3
- Pressure Drop - 2.9ft-hd @ 36 GPM
Notes:
- Valves should be selected based on the required flow rate, not connection size. For example, if you have a 5-ton heat pump with 1” connections, you should select the VQS5F and use a reducing fitting to go from 1-1/4” to 1”.
- The flow rate range for each valve overlaps the next size up; chose the valve that is closest to the pipe size you are using. In some cases you may chose to use all the same size valve on a job even when a smaller one will work for simplicity. For example, you may use the 1-1/4″ VQS5F for 2 ton units when you also have 4 ton and 5 ton units installed so that you can use one valve size for every unit on the job.
- This recommendation is for closed loop systems with a nominal flow rate of 3 GPM per ton. Check the heat pump manufacturer’s literature for actual recommended flow rate.
- This recommendation is for open loop systems with a nominal flow rate of 1.5 GPM per ton. Check the heat pump manufacturer’s literature for actual recommended flow rate.
- Pressure drop assumes water and is provided at the flow rate for the maximum Geo-Flo recommended nominal tonnage. When using an antifreeze solution either use Cv to calculate pressure drop or apply the appropriate antifreeze correction factor.
