Buckling Pin Pressure Relief Valve

BS&B developed the BPRV Buckling Pin Relief Valve, 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.

What is Buckling Pin?

Buckling Pin technology offers an accurate and reliable means of calibrating pressure relief devices. BS&B has developed the BPRV™ Buckling Pin Relief Valve for in-line pressure or vacuum relief offering quick and simple external resetting. The BPRV is suitable for both gas and liquid applications and provides a full relief opening at a pre-determined set pressure.

What is a Buckling Pin Valve?

The Buckling Pin Relief Valve can improve productivity within a facility by dramatically reducing the downtime that can be caused by other non-reclosing pressure relief devices. The BPRV is an in-line pressure relief device that offers a quick and simple field reset without removal from the piping system.

Operating Pressure Ratio

Buckling pin technology is highly resistant to operating pressure conditions. The BPRV runs at up to 95% of the minimum set pressure. This ratio is further settable with special testing.

Pressure Cycling Service

Buckling pin devices are well suited to cyclic service pressure conditions. When operating under compression, the buckling pin is not subject to tensile fatigue failure. The BPRV handles pressure cycles up to its maximum operating pressure ratio with negligible impact on service life.

Buckling pin devices are designed as non-reclosing ‘reclosable’ pressure relief devices. They are an alternative “non-reclosing” pressure relief device, usually rupture disks. Buckling pin devices are also an alternative to reclosing pressure relief valves, API series, and pilot-operated valves. They provide in-line pressure or vacuum relief, are easy to upgrade a rupture disk position, install directly between companion flanges, and offer quick and simple external reset, without opening flanges/piping.
