What it is
The Service Valve CH is a central heating isolation valve from Glow-worm, supplied under part number 0020211444. It is fitted to Glow-worm gas boilers across the Betacom, Easicom, Energy, Energy7, Essential, HOME and Sustain ranges. Its function is to isolate the heating circuit so that servicing, draining or component replacement can be carried out without disturbing the rest of the system.
