Okay, so the valve is kept open by the lower spring until the wax contracts or expands? At which point it opens further or starts to close respectively?
So how exactly does raising or lowering the wax element effect the temperature at which the valve closes?
Thank you for all the responses.
Okay thanks for the responses and the warm welcome to the forum!
On the diagram, is the spring in question the one between the two "0" ring seals, slightly above the valve disc?
Edit: is the spring visible in the diagram? And if so where is it?
Just a general educational question:
When one turns the control knob on a TRV to a higher or lower setting, what is it connected to within the valve? I assume it's adjusting spring tension or something similar?
(Assuming it's using a wax-based actuator.)
Thanks in advance.
