The relief valve type RV is a device to be installed on pipes or pressure vessels, which have the task of maintaining the pressure in the circuit below a certain range, absorbing and discharging outside small overpressure due to temporary events such as expansion of gas volume for increasing of gas temperature or back pressure shocks. Tanks to high flow rate and the compact design, these valves are ideal for civil and industrial users of natural gas, propane, butane, non-corrosive gases in general, and by a special execution for sewer gases as biogas. Installed downstream of the pressure regulators they prevent the action of shut off valves not depending from regulators damages or from overheating of the gas pipe with zero flow demand.
