The BS&B BPIV set pressure is controlled by a precision buckling pin which is calibrated to respond to the forces generated by inlet pressure acting on the valve disk independent of any back pressure that may be present. When the pin activates, the valve disc rotates to achieve the flow area.

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.
