Aluminum relief valve pmax 1 bar - Dn 1" F/F BSP calibration range 0.10÷0.16 bar

 

Relief valves are safety devices that discharge a certain quantity of gas outside when the pressure at the control point exceeds the calibration pressure (bubble burst pressure) due to non-lasting events such as the closing of valves of interception in a very short time and/or overheating of the gas with zero required flow rate. the discharge of the gas outside can, for example, avoid the intervention of the blocking devices for transitory causes not deriving from damage to the reducers. Obviously the quantity of gas discharged depends on the extent of the overpressure compared to the calibration. The operating principle of these safety devices is based on the comparison between the thrust on the diaphragm or piston deriving from the pressure of the gas to be controlled and the thrust deriving from the calibration spring. Obviously, the weight of the mobile unit, the static and dynamic residual thrusts on the armed pad also intervene in this comparison. When the thrust resulting from the gas pressure exceeds that of the spring, the shutter is raised resulting in the discharge of a certain quantity of gas; otherwise the shutter is released and closes the valve seat under the pressure of the pressure of the gas to be controlled alone and not of the calibration spring. In this way, damage to the reinforced pad due to incorrect adjustments of the calibration adjustment nut is avoided.
