APOLLO Flow Bypass Valve
A differential pressure bypass valve that redirects flow between the supply and return lines to prevent over-pumping when zones close — protecting boilers, pumps, and buffer tanks from the pressure spikes and flow starvation that can occur in a multi-zone system when only some zones are calling for heat.
