Pressure Relief Valve abbreviations

[DIY5]

I am trying to buy a pressure relief valve for a central heating boiler and do not understand the abbreviations associated with them. I see variants such as "MSV", "MSL", "MSM" and "MSML" etc. etc. Can anyone tell me what these stand for?

This is a safety device that should be fitted by a qualified person. He/she will know the correct PRV to fit.

you may think that you are saving money buying it yourself, but you cannot fit it yourself so will need a gas safe engineer to do so. if you were to supply the part yourself the engineer would most probably charge a premium and would very likely not guarantee it.
