Why use a regulator?
Certain Pro 86/88 burners, such as cyclone burners and most Promatic burners, require a steady pressure of 2 bar to ensure best performance. Other burners can also operate under high pressure, but it is an advantage to be able to stabilise and obtain the same pressure on both warm and cold days. The pressure in an LP-gas cylinder varies with temperature. If the gas output is high, the gas cylinder will be cooled down and the pressure will drop.

Why use a hose failure valve?
A hose failure valve improves safety by cutting off gas flow in case of a hose rupture or gas leak. The hose connection rotates freely on the valve housing, which helps prevent the hose from becoming tangled. (refer to 1811982)
