The OPW 71SO vaportight overfill prevention valve has received Phase I vapor recovery system certification (VR-102-H) from the California Air Resources Board. Designed to prevent the overfill of underground storage tanks by providing a positive shut-off of product delivery, the unit reduces installation time and costs by eliminating the need for messy and time-consuming epoxy sealants and provides a higher level of protection against the release of fugitive emissions and pressure decay failures.
