Rupture Pin

Over 16,000 valves have been sold throughtrained independent representatives around the world and have aremarkable 99.99% customer satisfaction rate. Here's some advantages of compare to rupture disc application:

Pins cannot fatigue. They buckle at set point. There is no yearly replacement required.
-------------------------------------------------------------------
Maximum operating pressure to 95% of set point. Zero leakage to set point.
-------------------------------------------------------------------
No downstream trash possible.

-------------------------------------------------------------------
No vacuum support required.
-------------------------------------------------------------------
More accurate set point.
1 PSI to 5 PSI +/- 9%
5 PSI to 70 PSI +/- 5%
70 PSI to 60,000 PSI +/- 3%
-------------------------------------------------------------------
Sense upstream pressure only OR differential pressure only.
-------------------------------------------------------------------
Installing a pin is so easy, it is hard to imagine doing it wrong.
-------------------------------------------------------------------
Pins are external to the process fluid and are made of corrosion resistant metals.
-------------------------------------------------------------------
Pins are rugged and can be stored at the valve.
-------------------------------------------------------------------
Pins are replaced by one person in only a minute, even with large valves.
-------------------------------------------------------------------
The pin has two conditions straight or buckled making it visuallyapparent. A highly reliable proximity sensor may be added to sense arising valve stem.
-------------------------------------------------------------------
Settings can be changed in minutes without breaking the line by using the "Poco" pin option.
-------------------------------------------------------------------
The pin is not system or ambient temperature sensitive.
-------------------------------------------------------------------
Buckling stress is much LOWER than yield stress.
-------------------------------------------------------------------
Pins are accurate and no vessel over-design is required.
-------------------------------------------------------------------
Rupture Pin valves have excellent performance and are worry-free.
