Answer: 
It is a manual over ride such that you can open the actual valve without having an electrical signal to the device. If you manually open the valve it will have the heat on (vlave open) unregulated. If you want the valve to work as a regulated valve again you will have to close the manual valve.

Answer: 
The operating lever allows you to manually open the valve. This valve utilizes a heat motor which can take a good 5 minutes to open and close. This lever allows you to quickly open the valve so that you can purge the zone.

Answer: 
No it can not. I was always curious about this too because they look so similar but are different in price. So I called a Taco engineer to ask about this a few years ago. The 5101-g2 and the other versions for geothermal applications have different ratings. Those systems have higher working pressure, temperature and flow rate. The valves and heat motors are different to meet this need. The power heads Read More

The 5101-g2 and the other versions for geothermal applications have different ratings. Those systems have higher working pressure, temperature and flow rate. The valves and heat motors are different to meet this need. The power heads for hyrdonic systems work at a much lower pressure temperature and flow rate. They are not interchangeable.

Rated 4.7 out of 5 by 6 reviewers.
Rated 4.0 out of 5.0 by Taco Power Head, Zone valve regulator the Taco head is a basic standard of the industry valve to regulate heat in a building by zones. It is easy to replace and reliable. In my case this was a straight up remove and replace, straight up same make and model. It was not especially cheap and seemed a bit on the expensive side and Home Depot is very convenient, saved me a trip across town to an actual plumbing/heating supply house. March 15, 2016
Rated 5.0 out of 5.0 by Taco Powerhead My heat was not working, so my first step was to replace the thermostat, It then worked for about a week intermittently. Sometimes it would turn on then sometimes not. Not a good situation for the New England winter. The next thing, I replace was the was the Taco Valve on the zone that was not working, It was as simple as putting a few low voltage wires on, and twisting off the old Taco Valve, and twisting on the new one. Heat work great now. February 10, 2016
