BS&B developed the BPRVTM Buckling Pin Relief Valve, available from HMA INSTRUMENTATION, for overpressure or vacuum relief requiring quick and simple external resetting. The BPRV is suitable for both gas and liquid applications. It provides a full relief opening at a preset pressure. Buckling Pin technology is a reliable and accurate means of calibrating pressure relief devices.

BS&B produces fast-acting, quick-opening Buckling Pin Activated Pressure Relief Devices (inline and angle discharge), designed to protect personnel, equipment, and the environment from the dangers of overpressure. Buckling Pin Pressure Relief devices combine the accuracy of rupture disks with the ability to be field-reset, while remaining installed after an overpressure event.

Buckling Pin Pressure Relief devices from HMA INSTRUMENTATION is a practical and proven technology for the protection of applications containing one or more of the following conditions: Continuous processing (fast reset in the line), hazardous service (limits operator exposure), large line size (convenient reset in the line), high flow capacity, inaccessible location (external reset in the line), high operating pressure to set pressure ratio, and sizes from 25 mm to 1 500 mm, in addition to cryogenic designs.
