In an hydronic HVAC system with a 2-pipe direct return setup, we use balancing valves to make sure each machine gets the right amount of water. Balancing valves are installed at the outlet and manually set to have desired flow rate (GPM). Once adjusted, the balancing valve stays in place to ensure each machine gets only the water it needs. Additionally, an automatic control valve, with the help of a thermostat in the air conditioning space, adjusts the flow of water based on air conditioning needs. Balancing Valve will not automatically adjust flow rate , we manually adjust balancing valve to setup the flow we want to have in that machine .
