I want to replace water flow control valve inside body

I want to replace water flow control valve inside body of old zone valve in my boiler hot water house heating system. I think this is called an "Actuator" (electrically operated valve). Original thermostats are Honeywell. Probably zone valves are, too. Over thirty years old. One zone valve (Zone 2 for upstairs) works fine, no leaks.

2020-8-16 · set your boiler temperature to 65°C in summer (between medium and low) and adjust down if your water feels too hot. If you have children, being able to control the hot water temperature is essential, as you can prevent scalding hot water from reaching the taps. It can also provide a boost in cold weather if your hot water is not quite hot enough.

Diverting Valve - an overview | ScienceDirect Topics

The three-port globe valve is usually used as a diverting valve in high pressure applications. Figure 3.23 shows a typical valve for hot, high pressure water used for boiler feed water. Flow is generally confined between two ports for the majority of operation; change-over is normally confined to start-up, shut-down or fault conditions.

107018 - Bell & Gossett 107018 - 1" Straight-Angle

Bell & Gossett 107018 - 1" Straight-Angle Flow Control - The Bell & Gossett straight angle flow control valve accomplishes two things. First the Flo-Control valve acts as a check valve, keeping the system flow from short-circuiting into places where it doesn't belong. Second, and just as important, the Bell and Gossett Flo-Control valve stops hot water from migrating into a zone that's not

Boiler Feed, Backflow Preventer & Combination Valves

2020-10-24 · These valves automatically feed water to a system whenever pressure in the system drops below the pressure setting of the valve. The dual control combines the boiler feed valve with an in-line pressure relief valve connected at the outlet end. The backflow prevents contamination of the potable water system if supply pressure should fail.

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.
