BS&B - Buckling Pin Relief Valves
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.
- Simple in-line installation
- Maximum relief capacity
- Convenient external reset
- Set pressure is unaffected by cycling/pulsating pressures
- Standard set pressures up to 275 psi
- Set pressure is unaffected by valve orientation
- The buckling pin is totally protected with a rugged enclosure
Set Pressure Range—Buckling pin technology is used for overpressure or vacuum relief at set pressures from a few inches of water column to over 1000psig.
Size Range—Valves are available for installation between all international standard flanges.
Temperature—Because the buckling pin mechanism is located in an external enclosure, the set pressure is unaffected by process temperature; only the ambient atmospheric temperature needs to be considered.
Operating Ratio—A 90% operating ratio permits process pressures up to 90% of the set pressure.
Service—Suitable for gas or liquid service. The selected seal material must be compatible with the process fluid.
Vacuum—Valves can be supplied to withstand vacuum. Inverted styles of the BPRV may be used for vacuum relief.
Pressure Cycling—Accuracy and reliability are maintained under pressure cycling conditions.
Leak Tight—As the operating pressure increases, the seal is progressively energized to maintain leak tightness. The seal is bubble-tight and offers minimal resistance to opening, permitting low set pressures and tight pressure tolerances.
U.S. Patent Number 6,367,498 applies; other international patents pending.
The Buckling Pin Relief Valve (BPRV™) offers quick and simple field reset without removal from the piping system.
The Buckling Pin Relief Valve (BPRV™) can improve productivity within a facility by dramatically reducing the down time that can be caused with other non-reclosing pressure relief devices.
The BPRV is an in-line pressure relief device which offers quick and simple field reset without removal from the piping system. This non-reclosing pressure relief device provides 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)
- Inaccessible Location (external reset in the line)
- Frequent Operation (fast reset in the line)
