Is it the actuator or the valve body itself??

Hi,

When replacing a 3 port diverter valve.

Is there a sure way to tell whether just the actuator needs replacing or if whole valve needs replacing? As i am not sure what to buy.

The diverter that needs replacing is a Danfoss HS3.


Any help would be greatly appreciated.

Thanks,
Casey

Just take the head off and see if you can move the spindle. It's very rare that the body needs changing as well although the HS3 aren't the best quality valves on the market.

Yes spindle seems to move fine. I shall just purchase the actuator.

Cheers Mike
