My bathroom radiator has a damaged Thermostatic Valve. I took it to a local DIY firm to look for a replacement. They informed me that I would need to know the manufacturer as different companies have different style connectors. I have attached a photo which shows the valve & connector. Can anyone advise who made the valve ? I am trying to avoid draining the system & putting on a new joint & valve if I can just replace the valve fitting itself. I live in then UK & the valve is up to 10 years old. It is connected to a 15mm right angle joint. Thanks in advance.
