FAIL-DRY® Concept

FAIL-DRY is a Plast-O-Matic patented design safety feature describing the unique concept of having a vented chamber separating two sealed sections of a valve or pump. In the event of lower (primary) seal failure, an upper (secondary) seal will continue to keep the operating media dry. Only controls with the patented FAIL-DRY feature offer this unique protection. FAIL-DRY permits a valve or pump to remain functioning after a primary seal failure, thereby keeping the process cycle or system operating until maintenance can be scheduled. This avoids costly emergency shut-downs. FAIL-DRY ® is a registered trademark of Plast-O-Matic Valves, Inc.
