Rupture discs and holders are commonly used in combination with pressure relief valves (PRVs). Due to increasing safety pressures on businesses, Elfab recognised the demand for a robust design to improve overall safety performance and sought to develop a technically superior rupture disc assembly (PRV-GARD), combining Elfab’s rupture disc ranges with an improved holder solution that allows safe opening of a rupture disc when installed before a pressure relief valve. With its increased face to face holder design, it ensures that full opening after burst is achieved, eliminating the risk of the disc protruding the holder; a significantly important factor when using a rupture disc and PRV in series.
In addition, the valve life is extended with the use of a rupture disc and holder in situ as using both helps to extend and isolate the contained media from the safety valve, allowing customers to benefit from cost savings in purchasing less exotic materials for the valve. Using Elfab’s new and improved combination design will not only improve maintenance schedules and support with emission control, it will increase overall safety performance and prolong valve expectancy. For those applications that require additional valve protection, Elfab will work to achieve a practical solution.
