15mm Compression or 1/2" Female
Danfoss Part No. 087N660800
Hi. It is suitable for use on central heating systems.
In the description, it states
"The spring return actuators have . . . "
Should this read
"These spring return actuators . . . ."
There is no technical information provided and the words "Spring Actuated" do not appear in the title.
With four wires it could be driven to open and close.
I require a spring return actuator and I am not sure this is a spring return actuated valve?
Can you clarify? Answers1
They are power (motor) to open, spring return closed.
It is a 4 wire as it doesn't have an earth.
Hi. Yes they are
That's correct. They are 1/2" with 15mm compression fittings included.
