Subject: Borg-Warner 3" and 4" Swing Check Valves
Dear Linda:
As we discussed over the last few weeks, Arizona Public Service advised Flowserve that a 4"-1500# Swing Check Valve didn't perform properly for the same reason that was earlier reported as a 10CFR21on a 4"-150# Swing Check Valve. A copy of the original report is attached.
Also attached is a copy of the letters sent to all customers who received either 3" or 4" Swing Check Valves of any pressure class during the time when the problem may have occurred. These are submitted per your request.
Please advise if there are any additional questions.
