BS&B Buckling Pin Relief Valves
Buckling Pin Pressure Relief Devices
For mer informasjon:
BS&B produces fast acting/quick opening buckling pin activated pressure relief devices (inline and angle discharge) designed to protect personnel, equipment and the environment from the dangers of overpressure. Buckling pin pressure relief devices combine the accuracy of rupture disks with the ability to be ‘fieldreset’ while remaining installed after an overpressure event.
Features and Benefits
Buckling pin pressure relief devices provide practical technology for the protection of applications containing one or more of the following conditions:
- Continuous processing (fast reset in the line)
- Hazardous service (limits operator exposure)
- Large line size (convenient reset in the line)
- High flow capacity
- Inaccessible location (external reset in the line)
- High operating pressure to set pressure ratio
- Sizes from 1 inch (25mm) to 60 inches (1,500mm)
- Cryogenic designs available
- ASME “UD” stamped, section VIII, division 1
- European Pressure Equipment Directive “CE” marked
- Back pressure independent options available (BPIVTM)
Operating Pressure Ratio
Buckling pin technology provides outstanding resistance to operating pressure conditions. The BPRV can be operated up to 95% of minimum set pressure. This is called the ‘operating pressure ratio’. Subject to special testing, there is the ability to increase this ratio further.
Pressure Cycling Service
Buckling pin devices are well suited to cyclic service pressure conditions. Operating under compression, the buckling pin is not subject to tensile fatigue failure. The BPRV can be cycled to its maximum operating pressure ratio thousands of times.
