Brownell’s new pressure relief valves are available in a wide range of sizes to prevent damaging pressure drops in a wide range of industrial applications. The devices are available to cater for flowrates from 0.1 up 10,000ltr/mn depending on the maximum differential pressure. Suitable for preventing the low pressures that can be destructive or cause malfunctions in equipment containers, storage vessels and pressure-sensitive instruments, they have the additional benefit of a built-in humidity indicator to monitor internal relative humidity. These units suit the many practical applications where a positive atmosphere of several bar within a vessel is the normal operating level and a negative pressure of just a few millibars could result in permanent damage. They will also protect equipment being transported in aircraft even under rapid decompression conditions.
