Cost Comparison Between Rupture Disks and Rupture Pin Valves
Over 4 Years

If you're ready to start saving money, get better performance, reduce downtime and lower your stress, take a moment to compare rupture disk costs vs. Rupture Pin valve costs over 4 years.

• When used as a stand alone pressure relief device
• 2" application at 250 PSI set pressure
• Assume Disk to Pin ratio 4 to 1 per year (15:4 over 4 years) - (Ratio as high as 32:1)

---------------------------------------------------------------------------------------------------------------------------------------------
32 Disks to 1 Pin Ratio = 11,087.00 MORE Over 4 Years
---------------------------------------------------------------------------------------------------------------------------------------------
15 Disks to 4 Pins Ratio =
5062.00 MORE Over 4 Years
---------------------------------------------------------------------------------------------------------------------------------------------

Why do rupture disks fail so often?
Disks are designed to fail early because the burst pressure is above the elastic limit. Our pins cannot fatigue and fail early because the buckling pressure of the pin is below the elastic limit.
