Remove TRV Valve Body

[pidgeon1]

How can I remove the Myson TRV Valve body. Whats my next move ??

I have prized the ring back off the fitted position, this holds the valve in position and the valve wont budge.
I think the valve is stuck at a low temperature.

This happen with another make TVR and a squirt of ballistol oil on the valve pin and a few presses released this.

To remove the head,turn to high and undo the large ring securing to the body. To remove the body drain system and undo the two chrome 1/2 inch unions.

My Problem is I have pushed back the ring but unable to pull off the head, maybe if I use a flat blade or wide screwdriver to prize off the head ?

Once the large ring is un done it should pull off

Thats what I thought but it's Not happening !!

Maybe warm with a hairdryer to softer grips holding head on ?

Will try the broad blade/screwdriver to try to ease off on Tues
