Ive been in the field about three years and am still learning the basics. Can anyone direct me towards any info on how hydronic heating flow control valves (for multiple zone systems) operate? Much obliged!

    i guess its easy to describe as a weighted check valve with a manual opener. when the pump starts, it lifts the check, when it stops it allows the check to return to the closed position. this keeps zones from receiving gravuty flow which could cause overheating, especially in mild weather. if you were to have some reason to not use the check valve, the manual overide on top will allow you to manually open the valve. this could come in handy during a power failure, you could open the valve and allow any heat left in the boiler to heat the house for a short period of time.
