Looking for good quality 1/2 GB trv that's bi flow

[bright spark]

Hiya lads as d title above suggests I'm looking for a good quality bi flow gb trv.
It must have a long body. The one I'm taking out is approx 45mm from centre of rad connection to bottom of valve.
Original installer fitted a load of valves in building back t front.
Original TRVs much longer than lock shield valves so it'd mean a lot of cutting and screwing in offices if I was just gonna swap em round.
I usually use a Pegler gb valve for bi flow buts it's body is too short.
Any suggestions would be appreciated
