Taco Sentry Quiet?

MattD

I need to replace some existing Taco ESP zone valves on a residential hot water system with radiant fin tube baseboard heat, all lines are copper. The Taco ESP zone valve makes a whining/squealing sound every time they open or close and they have been making this noise since they were installed about 10 years ago. This sound resonates well over the copper pipe and fin tubes and you can hear it no matter where you are in the house. From my understanding the valves are supposed to make this noise due to the actuator motor and gears.
The simple solution would be to replace the ESP actuators with the new Taco Sentry actuators, but I am wondering if the new Sentry actuators make a similar noise. Any comments?

I've found the Sentry's very quiet.

Sentry has no noise issues that I have encountered . Hundreds of em and no noise complaints yet .

Hi Matt
Zone sentry replacement actuator ZA024Q4A1, will replace the old style ESP actuator. It is much quieter, and more robust than. No tools required for change out. I encourage you to try the new sentry, and you will agree it's much quieter.

if you prefer totally quiet valve, the Taco 570 series heat motor valve will be a suitable option. If you decide to go that route, you will need to replace the entire valve; hopefully this was helpful.

If you have additional questions feel free to get back in touch with me at Taco. thanks
