BOLINGBROOK, Ill. — Hansen Technologies Corp. announced that it recently discovered that certain pressure relief valves sold to customers for industrial use from Feb. 16, 2011 to April 4, 2013 are more susceptible to internal corrosion when exposed to standing water inside the valve. Even though the risk is remote, the failure of a pressure release valve could conceivably result in serious personal injury and/or property damage. Consequently, Hansen has initiated a program to send replacement valves so that any valves currently at risk can be replaced promptly. Hansen said it has not received any reports to date of any valve failures that have resulted in personal injury or property damage, but it is taking this action in the interest of safety and avoiding potential risks. The company therefore is issuing this recall of all valves that may be potentially impacted.

Specifically, Hansen H5600A, H5601, H5602, H5600R, H5602R, and H5632R valves with serial numbers 02B11 through 04B13 are susceptible, regardless of pressure setting.

If your valves have any of the model and serial numbers noted above, contact your service provider, contractor or company from which you have purchased these valves. If you have distributed the above-referenced valves to other parties, notify those parties promptly so that they can take the steps outlined in this announcement.

This recall does not apply to H5613, H5604, H5633R, H5634R and EZ-SRV relief valves.
