Great Product!
I installed two of these valves on my boilers hot water system. They work really great. It stopped the water from bleeding through my baseboard in the up stairs rooms when the thermostat was off. What really made the job easy was the valve could be put on the vertical. That saved me so much time. I would recommend these valves.

Just what I needed
I needed to replace a noisy control valve and decided to try the Hydro Trol valve. It works perfectly and makes absolutely no noise. Additionally, the valve has a very simple and effective design.

Q: I plan on installing Danfoss TRV's on each radiator. Each radiator will be plumbed with 1/2" pex using the home run method. The supply and return attach to 1-1/2" manifolds. What type of valve should I use to balance the system? Or can the TRV be used for this? Please advise
