Bard 8603-011 - 5 GPM 3/4 in constant flow valve

The Bard 8603-011 constant flow valve is an OEM 5 GPM regulator designed to maintain the correct water flow through Bard water source heat pump piping even when incoming water pressure varies. This 3/4 inch valve is installed in the water circuit in the direction of flow indicated on the valve body arrow and is specified for applications where a controlled, consistent loop flow rate is required for proper heat transfer and stable unit performance. Bard literature notes that adequate pressure must be available ahead of the valve for proper operation, so confirm your system has sufficient available pressure and match the valve to the unit’s rated flow before ordering.
