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. Set pressure is unaffected by cyclingpulsating pressures Set pressure is unaffected by valve orientation The buckling pin is totally protected with a rugged enclosure.

An explosion can result from an ignition of a combustible gas, mist or dust when mixed with air during processing, handling or storage operations. A rapid rise in pressure occurs in the containing structure, and if it is not of adequate strength to withstand the deflagration pressure, extensive damage and injury to personnel can occur. Explosion vents are low burst pressure membranes of calculated area fixed over an opening on the structure to be protected. In the event of a deflagration the vents provide a rapid and unrestricted opening at a predetermined burst pressure (Pstat) allowing combustion gases to expand and flow through the open vent. The required relief area necessary to protect plant or equipment may be determined by using the most current standards of NFPA 68 or VDI 3673.

The SKR-U™ rupture disk (bursting disc) is partnered with the UR-2 safety head to provide high integrity reverse buckling rupture disk (bursting disc) technology in a threaded union type holder. The SKR-U™ rupture disk (bursting disc) uses Saf™ technology (structural apex forming) to accurately control its burst pressure making it insensitive to the assembly torque variations that will occur in a threaded type holder. The UR-2 safety head is available in three standard nominal sizes: 12 " 15mm, 34_" 20mm, and 1" 25mm. Standard inlet & outlet female threads are 12 ", 34 ", and 1" NPT. Custom thread configurations are available. The SKR-U™ rupture disks (bursting discs) are identified SKR-U™12" 15mm, SKR-U™34" 20mm, SKR-U™ 1" 25mm and are all supplied with permanently attached 3-D metal identification tags.
