BS&B RB-90 Safety Pressure Relief Rupture Disk

The BS&B RB-90 Safety Pressure Relief Rupture Disk is a high-performance rupture disk designed to protect vessels, pipelines, and systems from overpressure conditions. The RB-90 rupture disk features a robust design that provides a quick, reliable, and controlled burst response to relieve pressure in the event of an overpressure situation. It is engineered with precision for safety-critical applications in industries such as chemical processing, pharmaceuticals, food production, and oil & gas.

This rupture disk is constructed with a combination of 316 stainless steel and FEP (Fluorinated Ethylene Propylene), providing excellent resistance to corrosive environments and high-performance capabilities under extreme temperatures. The RB-90 model is engineered to handle a broad range of pressure applications, with a pressure setting of 108/111 PSI at standard conditions. The material selection ensures durability and long-term reliability in challenging environments.

The RB-90 rupture disk is designed to activate and relieve excess pressure quickly and efficiently, preventing potential damage to the equipment and ensuring the safety of personnel. After activation, it is a one-time-use device and must be replaced.
