While the LPG pressure relief valve is one of our ‘classics’, the Proxy Valve (PV) version is an adaptation and improvement on it. Actually, this could even be considered a ‘modern classic’ as they have been in circulation in certain countries since 2009.
If you are reading this, you already know your stuff, but we can still start with some basics about relief valves. Alternatively, how about going deeper into the in-depth technical paper about the valves attached here as a PDF.
Pressure Relief Valves are one of the most important parts of the LPG tank equipment. In the unlikely event there is an over pressure build-up, these valves release the excess pressure into the atmosphere.
In a normal operating position, these LPG valves are held closed by the force of a spring. If the pressure in the container increases above the rating of the spring, the pressure relief valve opens to release gas until the pressure falls below the spring rating in which the valve closes.
But as the main title explains, the regulations can make maintenance and managing your equipment, as well as time and resources, a vital part of the process. This is where the Cavagna Group Proxy Valve (PV) series comes in.
