Danfoss HS3 3 Port Motorised Valve is rated 4.0 out of 5 by 3.
Rated 3 out of 5 by from Not reliable in the long term! I first fitted this valve to our central heating 20 years ago. It took 10 years for the electrical actuator to wear resulting in the unit failing to properly complete its activation... click, click, click, as the motor repeatedly tried to complete its task. Bought a new one and changed the electrical actuator only... but noted (when cold) that the valve spindle was weeping very slightly. The replacement electronic actuator has now failed with exactly the same problem... The valve spindle is leaking excessively so I have ordered another manufacturer's product in the hope that I won't have to attend to this matter again!

Rated 5 out of 5 by from superb product this is a replacement for another well known make which the shoe continued to stick when changing positions causing a loud bang ! The Danfoss product is well engineered and hopefully will last. Finally the wiring diagram supplied could be more detailed
