Good advice!!!This is what you want:
> New Heater Control Valve <
The original uses a rubber diaphragm which splits and leaks. I've owned my TR4A 24 yrs now and blew out two of em. Until I installed this. It uses a metal ball valve. Almost full proof.

I have the same heater valve and yes, it is a great upgrade to the original.
I also removed the steel ball from the control cable. Now I can set it at an infinite position.
