Balboa high water-speed flow regulator for heat pumps

This Balboa control valve is used in conjunction with a bypass circuit, to maintain the speed of water flow within the recommended limits for a Clim8zone heat pump. It designed for use on any plumbing circuit that uses pipe diameters of 50 mm or less (including 1.5-inch), and also for pumps with a power rating of between 1.5 kW and 3 kW, regardless of the size of the pipe.

If you are using fatter pipe (such as 63 mm or 2-inch) and a pump with a power of 1.5 kW or less, then you should use the low-velocity flow regulator instead.

If you are using a pump that is more powerful than 3 kW, then you should add a separate, manually-adjustable valve to reduce the flow rate through the heat pump. Please contact us for more information.

Dimensions
Internal diameter: 60 mm, for 2-inch pipe. Use reducers if you are connecting 1.5-inch pipe
Diameter of the window that holds the spring in place : 23 mm
Length: 160 mm
External diameter: 70 mm

Part numbers
Balboa: 73002
The reference UL FILE E145689 is indicated on the valve but this is also the case for the low velocity control valve. It is essential to measure the diameter of the window that holds the spring in place to determine which valve it is (refer to picture no. 2).
