Additionally a flow control valve prevents zones from overheating due to gravity circulation. The second valve also known as the main valve allows gas to flow to the burner trays. It is also installed to prevent overheating of individual heating zones by gravity. The hydrotrol ht flow control valve a specialty check valve e is used to prevent hot water from circulating through a building where the boiler is kept on to provide domestic hot water via a tankless coil or indirect water heater during non heating season months.

Flow control valves regulate the rate of fluid in plumbing and heating systems. Designed and engineered for reliability and built with all the quality you expect from taco these zone and flow control valves are used to create and control individual zones or isolate equipment in a hydronic heating system.

Gas valves help to control the flow of gas within a system ensuring that everything runs according to plan.

The primary valve also known as the safety valve supplies gas to the pilot light. Some flow control valves act as a check valve preventing fluid from drifting into places where it doesn t belong or zones that are not calling for heat. Zone and flow control valves.
