Vacuum Overflow Valves
...Feature Innovative Engineering to Save Money
and Increase Scrubber Overflow Reliability
New Bionomic ScrubSeal Vacuum Overflow Valves are the perfect overflow
and vacuum seal solution to replace troublesome manometer water seal legs
on scrubber sumps.
Designed to eliminate unreliable, cumbersome manometer piping, and the
headache of maintaining a liquid filled line, ScrubSeal acts as a check valve
to allow drainage of scrubber sump liquid through the overflow valve while
maintaining required vessel vacuum during normal non-flow conditions.
As an added safety feature, ScrubSeal prevents unrestricted rise of the liquid
level within the vessel, a situation that can cause structural damage from
excessive hydrostatic pressure – resulting in potential costly damage
to downstream equipment, or product contamination due to
scrubbing liquid passing through the horizontal gas inlet.

...Offer a Number of Other Important Features and Benefits
Ease of Installation
ScrubSeal Valves are designed for use in either vertical or horizontal pipes
and inline or end of pipe mounting.

Wide Range of Sizes
ScrubSeal is available in five sizes from 3/4˝ – 4˝ to accommodate a wide
range of overflow rates from fractional to over 500 gallons per minute.

Choice of Construction Materials
ScrubSeal Valve bodies are manufactured in corrosion-resistant
polypropylene (PP), polyvinyl chloride (PVC), or chlorinated polyvinyl chloride
(CPVC) depending upon size with durable, flexible EPDM internal elements to
withstand many cycles of use.
