A flow control valve for a bathing installation. The flow control valve is configured to operate between an open state and a closed state in dependence on the applied water pressure. As water pressure increases, the valve progressively reduces flow dynamically, until flow increases to a point that the valve is placed in the closed state. The valve may be placed in the bathing installation recirculating water path downstream of a bypass path and upstream of a heat pump. By regulating water flow and pressure to the heat pump, the heat pump may be operated in a flow rate for efficient operation. The valve also prevents water pressure at a high level which may damage the heat pump.
