Elfab develops new Buckling Pin Relief Valves

Published by
Hydrocarbon Engineering,

Elfab has expanded upon its range of rupture discs and explosion vents with the introduction of Buckling Pin Relief Valves (BPRVs). This latest partnership further enhances Elfab’s pressure relief options for applications within safety critical process environments.

There are two non-reclosing primary pressure relief devices, rupture pins and rupture discs, both offering a range of advantages dependent on specific pressure relief applications and conditions. Having both technologies under its pressure intelligence brand better positions Elfab to service its global customer base in providing the most cost effective, safety critical pressure relief solution. The BPRV is a unique product that offers an accurate and reliable means of pressure relief calibration, whilst also enabling resetting without the need for the valve to be isolated from the process.

Each Buckling Pin is uniquely designed and manufactured under the highest quality standards to meet customer’s individual applications. Unlike other forms of pressure relief devices, the critical component (the pin) is located externally and isolated from the process. At a set pressure the pin buckles instantaneously allowing the pressure to be released. With two simple states (straight or buckled), after functioning the pin is the only element that needs replacing, avoiding human error occurrences due to ease of installation while benefiting from low replacement costs.

BPRVs are almost maintenance free and not subject to annual replacement. Suitable for a range of applications and industry sectors such as petrochemical, oil and gas, food processing, energy and pharmaceutical; buckling pins are long term cost effective solutions for a vast range of pressure relief requirements.
