WebSelf-actuating, this valve automatically and continuously adjusts flow to maintain the specified temperature at the fixtures. When the specified water temperature is satisfied, the valve closes, allowing only a small flow bypass to the return line. This constant low flow rate prevents dead-heading the recirculation pump. WebBypassing Although not very common, the bypass is basically applied to rotary pumps. The discharge flow to the system is reduced by bypassing part of the pump discharge flow to the pump suction, meaning that the total flow increases (from 10 to 12.4) but the head decreases (from 10 to 6.6). Relative power consumption is equal to:
