Accessories
BS&B supplies many of the Accessories required to safely and conveniently install our overpressure relief devices and complementary products. Through our professional team and global network of sales engineers and procurement personnel, we are able to provide the highest quality accessory products to meet your installation requirements.
Saf-T-Pin™ Buckling Pin Cartridge
The BPAV can be provided with buckling pin cartridges that are installed like an electrical fuse. The Saf-T-Pin buckling pin cartridge allows a “quick-change” option of buckling pins with a simple push-in/pull-out design for installation within the enclosure. Each Saf-T-Pin cartridge contains a calibrated buckling pin that is perfectly mounted for optimum performance.
Replacement Buckling Pins
Stainless steel pins with tags containing pressure and traceability information including the serial number of the BPAV device.
