Hot Water Boiler Piping Zone Valves - Thermostats and Zoning. A zone valve is hooked directly to a thermostat. On a call for heat, the thermostat contacts close completing the circuit to the zone valve and energizing a small motor in the zone valve. This motor opens the valve. As the valve opens an end switch in the zone valve closes.Learn More

Feb 19, 2021 · Taco Flo-Cheks are used in a forced hot water heating system to prevent gravity circulation during periods when the boiler is hot but the space heating zone is not wanted. This makes it possible for the use of the heating boiler to maintain domestic hot water year round.Learn More
Mar 27, 2020 · The flow control valve on a boiler regulates the flow of hot water to the system. It is part of the hot water supply side of the boiler and one of the major components of a hot water boiler. A basic flow control valve opens and closes to adjust the rate of water in the boiler. There are different types of flow control valves on the market, including needle, ball, diaphragm, plug …Learn More
Feb 10, 2015 · The valve maintains a pathway for the water to flow back to the boiler(s) when the coils are not operating and their own 2-way valves are closed. Remember, a certain amount of flow is also necessary prior to boiler start-up and following boiler shutdown so that all the minimum flow requirements are met during these brief periods.Learn More

9. Multiple boilers and storage tanks shall be installed with reverse return piping (as shown). 10. Mixing valves are recommended on all tanks if hot water temperature is above 119oF. 11. Expansion tank must be rated for use with potable water. 12. Use either indirect/tank sensor or system/pipe sensor mounted on common return to the boiler. 13.Learn More
Oct 25, 2011 · It appears that the flow is reversed through the boiler. The supply water should come out of the top tapping and return into the bottom tapping. I find it a bit odd the way they piped those flow control valves. They could have just entered the bottom tapping instead of using in elbow into the back.Learn More
Two port control valves are used to control water flow to a process, for example, for steam boiler level control, or to maintain the water level in a feedtank. They may also be used on heat exchange processes, however, when the two-port valve is closed, the flow of water in the section of pipe preceding the control valve is stopped, creating a Learn More

Additionally, a flow control valve prevents zones from overheating due to gravity circulation. Gravity circulation occurs during periods when the boiler is hot, but the heat is unwanted in a zone. This allows the boiler to be preset so you can maintain domestic hot water year-round.Learn More

Hot water heating systems (Figure below) transport heat by circulating heated water to a designated area. Heat is released from the water as it flows through the heating unit (coil, terminal). After heat is released, the water returns to the boiler to be reheated and recirculated. Low temperature hot water boilers are ≤ 250°F.Learn More
Plastic Threaded Flow-AdjustmentValves with Garden Hose Outlet. For lightweight and corrosion-resistant alternative to metal, these valves are plastic. Attach garden hose to the valve outlet. Use with water. These valves gradually open and close to adjust and regulate flow.Learn More
Boiler Piping Flow & Pipe Sizing - It is important that the correct pump is selected in hot water boiler loops so that the correct velocity is achieved throughout the system. Too much velocity and the system will not be efficient because of Laminar flow issues. Not enough velocity and the correct amount of BTUs will not be delivered throughout Learn More
