Replacement Contract Head for Myson TRV 2-way Thermostatic Radiator Valve
To fit the head – set the arrow (triangle) to the fully open position (black dot), engage the head firmly on to the valve body, screw the knurled ring securely to body
The Metal ring at the base of the head has a 30mm thread.
Myson did make a TRV 2-Way thermostatic radiator valve body with a 28mm thread at one stage – if your valve has a 28mm thread Myson do make an adaptor to allow the head to fit on to the 28mm valve body.
